FORMER Forest Green striker Jon Parkin has called time on his playing career.

The 37-year-old former Barnsley, Hull City, Stoke, York City and Preston frontman announced his retirement on Twitter.

He said: “It’s come to that time in my career where no matter how hard I try, I simply can’t run the 100m in under 10 seconds anymore.

“I always knew once my pace went that I could never be the same player so I’ve decided it’s time for me to hang the boots up.

“I’ve done 21 years so I can’t really complain.

“Not 100 per cent sure but think it’s around 670 games and 225 goals which ain’t too bad for a fat lad from Barnsley.

“On to pastures green. It’s been an absolute pleasure.”

Parkin joined Rovers from Fleetwood Town in 2014 and scored 44 goals in 96 appearances for the club.
