Gloucester-born winger Zack Kotwica has signed on a non-contract basis after a summer of trials up and down the country, including with Brighton & Hove Albion`s under-21s and National League outfit Barrow AFC.
Kotwica was released by National league champions Cheltenham Town last season.
Now 20, he spent last term on loan at Cirencester Town in the Evo-Stik League Southern Premier Division and will now return to the Tigers, for whom he appeared on loan during the 2013/14 campaign. He has also appeared for Bishop's Cleeve on loan.
Kotwica made his League debut for Cheltenham against Burton Albion in a 2-2 draw in August 2013.
His first goal was a spectacular strike at Mansfield Town the following season and he also netted against Luton, making nine starts and twenty-six substitute appearances for the Robins in League Two.
