The decision came after the umpires inspected the field of play shortly after 11am.
There will be an inspection at 9am tomorrow to ascertain the chances of play tomorrow morning, with all developments relayed as they happen on the the official website and via the club's Twitter feed.
Despite no play on Day Two, Day One was an action-packed affair and highlights can be viewed here.
The decision comes after Derbyshire revealed to Park that he would not be offered a new contract at the end of the current campaign.
Park made 1000 First-Class runs in his first season at the County Ground, averaging 42.38, going onto represent Derbyshire 29 times.
Derbyshire's 400th First-Class match at Queen’s Park lived up to its billing with an action-packed opening day of Derbyshire’s top of the table clash against Yorkshire.
Having bowled the visitors out for 219 inside the first two sessions, Derbyshire then reached 135-7 at the close; a deficit of 84 runs with three wickets remaining.
With the visitors winning the toss and electing to bat first, the match got underway on time against a backdrop of clouds and patchy blue sky.
The context of the local derby fixture could not be more fascinating with both sides battling for promotion from Division Two as the business end of the season approaches.
Derbyshire have enjoyed an excellent first half to the campaign having established a 25-point lead over second-placed Yorkshire with seven matches to go.
Derbyshire return to LV=County Championship action this Wednesday, July 18th, in what is arguably the county’s most important four day match in years.
With the White Rose county relegated from the top tier of the domestic game in 2011, the prospect of an LV=County Championship encounter at Queen’s Park, Chesterfield, was always a mouth-watering proposition.
However the current context could not be more fascinating, with both sides battling for promotion from Division Two as the business end of the season approaches.
Usman Khawaja hit a maiden one-day century for the Falcons as the hosts began the Chesterfield Festival of Cricket with a 35 run win over the Unicorns at Queen's Park.
The Australian Test international was in fine form, hitting 104 after Derbyshire had lost the toss and asked to bat first; the hosts reaching 235-7 before a Mark Turner-inspired Derbyshire bowled the visitors out for 200.
The Falcons began brightly with openers Chesney Hughes and Khawaja looking comfortable at the crease; the pair progressing the Derbyshire score to 50 without loss after ten overs.
Poynton, who has missed the last two games, had further scans this week and remains a doubt ahead of the forthcoming Chesterfield Festival of Cricket which takes place this week.
“Tom's injury is taking slightly longer to recover than first anticipated,” Head Coach Karl Krikken explained.
“Chris Durham has already come in and done a good job for us. However, we felt it would be wise to add a little more experience in this critical area of the squad ahead of a busy period of cricket."
The Falcons had earlier reduced the hosts to 220-8 from their 40 overs before reaching 19-2 before the rain came.
Having won the toss, the Falcons opted to bowl first and the decision looked a good one with openers Kyle Coetzer (9) and David Willey (21) dismissed by Mark Turner inside the first ten overs; the latter caught at the wicket to give Chris Durham his first victim in CB40 cricket.
The headline show of five days versus Yorkshire may be still to come – but Derbyshire Head Coach Karl Krikken is anticipating an entertaining Chesterfield Festival opener versus the Unicorns this Sunday (1.45pm start).
Krikken believes Queen’s Park is the perfect setting for limited-overs cricket and he’s determined to start the festival with a bang.
“We’re all looking forward to an exciting week of cricket and it’s the Unicorns first up,” he said.
“They will be our immediate focus; they’ve surprised counties in the past and we’re determined it won’t happen to us on Sunday.
