Tim Groenewald has advised Derbyshire of his intention to leave the Club at the end of the season.
The Club have waived their right under ECB rules for 28 days notice to allow the player to speak to other Counties.
The 30-year-old has played 72 first-class matches for Derbyshire and taken 229 wickets, at an average of 29.
He has also taken 103 wickets in limited-overs formats and was capped by the Club in 2011.
Elite Performance Director Graeme Welch said: "Tim has been a terrific player for Derbyshire and we respect his decision to move on.
"We are absolutely committed to our long-term vision for success and we have an exciting crop of young seam bowling talent coming through with the likes of Ben Cotton, Tom Taylor, Matt Higginbottom and Greg Cork.
Derbyshire return to red ball action tomorrow as they continue their LV= County Championship campaign in the rearranged fixture against Leicestershire at Grace Road; 11am start.
The original fixture, due to take place on April 6, was postponed due to a car accident that tragically killed wicketkeeper Tom Poynton’s father, Keith.
Derbyshire enter the rearranged fixture on the back of a spirited four-day performance against Division Two leaders Hampshire at the Ageas Bowl last week, despite hanging on in a rain-affected final day.
Graeme Welch has named an unchanged squad for the LV= County Championship clash at Grace Road.
Despite a half-century for Marcus North, Nottinghamshire Outlaws claimed a five-wicket win in the NatWest T20 Blast fixture at The 3aaa County Ground.
North top-scored with 57 as Derbyshire posted 164-7 off their 20 overs, but a blistering 63 from Alex Hales guided the Outlaws to victory.
It was a difficult start for the Falcons, who slipped to 23-3 after 4.3 overs in the face of some good bowling from Harry Gurney (2-24) and Andy Carter (2-42).
But Captain Wayne Madsen led from the front hitting 36 off 27 balls (3 fours, 1 six) as he sparked the Derbyshire fightback. He was ably assisted by North who, when Madsen fell, carried the mantle to top score with 57 off 47 balls (6 fours).
Scott Elstone chipped in with 17 off 10 balls to help move the hosts to 139-6 in the 18th over. Signal a late onslaught from Tim Groenewald who hit 19 off just 7 balls (3 fours, 1 six) to help his side reach a competitive 164-7.
Derbyshire Falcons continue their NatWest T20 Blast campaign against local rivals Nottinghamshire Outlaws on Friday at The 3aaa County Ground; 7pm start.
Wayne Madsen’s men are aiming for a repeat of their victory at Trent Bridge in 2013 against an Outlaws side armed with a hugely talented squad including England’s Twenty20 opening pair, Michael Lumb and Alex Hales, plus fellow internationals James Taylor, Samit Patel and Chris Read.
Graeme Welch has added young pace bowler Tom Taylor to a 15-man squad for the visit of neighbours Nottinghamshire.
Supporters will be able to clock their bowling speed at The 3aaa County Ground as part of the family-fun on offer throughout the evening. Other family-fun activities will also be available including bouncy castles and entertainers. Supporters will also be able to collect autographs from their favourite Derbyshire players straight after the conclusion of the match.
Live band, The Fentones, will also be playing instantly recognisably catchy tunes immediately after the match in the Marquee for supporters to enjoy.
Tickets for tonight's local derby between Derbyshire Falcons and Nottinghamshire Outlaws at The 3aaa County Ground will be available on the gate.
Advanced sales have already reached their highest levels of the Twenty20 era with the exception of last year’s sell-out; and, with the improved weather forecast, there will still be an opportunity for supporters that make a late decision to attend.
Supporters can still reserve their tickets ahead of tonight's game at the on-the-day price, Adults £18 and Juniors £5, by calling the Ticket Hotline on 0871 350 1870 or visiting the Gateway Centre; Grandstand Road, Derby, DE21 6AF.
Gates will open at 5pm with the match starting at 7pm and supporters are encouraged to arrive early to avoid congestion and take advantage of the entertainment which will include music, bouncy castle, bars, food zones and an interactive area for spectators to bowl and clock their miles-per-hour.
Last year more than 21,000 current and former players responded to the survey – the first of its kind ever undertaken by ECB - and the national governing body is already acting on the comprehensive and wide-ranging feedback received.
Clubs and leagues nationwide are introducing new formats, rule changes, different start times, shorter travel distances to matches and greater opportunities for women, girls and people with a disability to play the game.
Examples of change at county level since last year’s inaugural survey include:
Wes Durston says the squad are determined to kick-start their NatWest T20 Blast campaign with victory over local rivals Nottinghamshire Outlaws on Friday.
The Club are expecting a bumper crowd at The 3aaa County Ground as Wayne Madsen’s men welcome an Outlaws side including internationals Michael Lumb, Alex Hales, Samit Patel and James Taylor.
Durston is hoping Derbyshire can repeat the result from Trent Bridge last summer when an unbeaten 50 off 25 balls from Durston himself helped the Falcons claim a 16-run win.
“Notts game is a fixture the players always look forward to,” Durston said. “We want to do well and especially against Notts.
“There’s no better way to kick-start our season than a win over our local rivals.
“The weather looks good for tomorrow and we’re looking forward to it. But there’s no doubt that it’s going to be a tough game. Notts are a very good Twenty20 side. It’s going to be hard and we are going to have to play very good cricket, but we are confident that we can do that.
“Last year’s game at Trent Bridge was a memorable match,” Durston added.
Hampshire dominated the final day, but a spirited Derbyshire lower-order, led by David Wainwright and Alex Hughes, survived to salvage a draw at the Ageas Bowl.
Rain washed out the morning session, but when play finally got underway at 2.30pm, Derbyshire endured a disastrous period of play in which they lost five quick wickets.
In favourable conditions, James Tomlinson (2-16) and Matt Coles (2-22) produced a devastating spell of seam bowling to reduce the visitors from 31-0 to 51-5 at Tea.
Wainwright and Hughes, however, stemmed the surge of wickets with a spirited 43-run stand in 11 overs after the restart. The pair batted admirably before Wainwright was seventh man out for 22, with Derbyshire 94-7 with 22 overs still scheduled for the day.
Tony Palladino (2) was eighth man out, but Hughes (18 not out) remained firm despite the toppling of regular wicket. New batsman Tim Groenewald (4 not out) remained with his younger partner before rain returned to stop play with 15 overs still left.
Graeme Welch says the squad enter Friday’s NatWest T20 Blast derby against Nottinghamshire with the belief that they can kick-start their campaign.
Welch says the squad are all looking forward to this Friday's NatWest T20 Blast clash and hopes they can get their campaign back on track with a good performance against their local rivals.
“The games come quick and fast and the lads are 100 per cent looking forward to resuming the old rivalry against Notts,” Welch said. “It should be a packed house, good crowd and hopefully we can perform as we know we can, put on a good show and get a good result.
“Momentum is a key word in Twenty20 cricket and if we can get on a roll then we can still have a successful campaign. Every game we go in to we try to win. We’ve had a few good days in Hampshire and hopefully this can give us the confidence against Notts and for the rest of the campaign.
