Notts seamer AJ Harris will be released by the club when his contract expires at the end of the season.

The 35-year-old has fallen behind new arrivals Darren Pattinson and Andre Adams in the pecking order after suffering an injury setback in pre-season.

But he has made a determined recovery in pursuit of first team cricket and, after a brief loan spell at Gloucestershire, he has joined Worcestershire.

Harris is currently helping his adopted county's LV County Championship Division Two challenge, who hold a 20-point lead at the top.

"AJ has served Notts well for nine years and he can count himself unlucky this year because our seam bowlers have managed to stay injury-free," said Notts' director of cricket Mick Newell.

"He's full of effort and commitment and he contributed a lot, particularly to our four day side, during his time at Trent Bridge.

"He still has a great appetite for the game and he can certainly perform a role for another county, but we want to give opportunities to younger bowlers."

Harris is currently enjoying a benefit year and was the recipient of the gate receipts from Sunday's NatWest Pro40 game against Sussex.

He joined Notts from Derbyshire in 2000 and was a key component of the side that won the County Championship in 2005 with second-innings figures of 6-76 in the decisive fixture against Kent.
