Nottinghamshire have agreed to release Jason Brown from his contract.

Brown had a year to run on the two year deal he signed when he arrived at Trent Bridge from Northants at the start of the season but is now free to pursue a deal with another county.

The right-arm spinner was hampered by a calf injury during his time at Notts which prevented him from playing a major role in the Twenty20 Cup.

“Jason was unfortunate to suffer injury at a time when he could have played a significant part in limited overs cricket but we feel that the time is right for him to move on given the signing of Graeme White,” said Nottinghamshire Director of Cricket Mick Newell.

“It has been a frustrating year for him but there was no lack of effort on his part and I’m sure he’ll find another county.  We wish him every success for the future.”

Brown joined Notts at a time when both Samit Patel and Graeme Swann were heavily involved in the England squad but now hopes to play regular cricket elsewhere.

“I’ve enjoyed my time at Trent Bridge but at this stage of my career I need to play regular cricket,” said Brown.

“I’m over my injury and I want to be in a position where I can begin next season in contention for a place in a county first team.”
