Previous Club Notts County
Experienced centre-back Hollis joined FGR on an 18-month contract in January 2018 after terminating his contract with Notts County.
The 25-year-old came through the academy system at Meadow Lane, making his debut in January 2012 following a loan spell with Barrow at the start of the 2011/12 campaign.
He ended that season on loan at Darlington, where he made nine appearances, scoring once, before working his way into the Notts County first team the following season.
Hollis was a near ever present during the 2014/15 campaign, making 47 appearances in all competitions and went on to make 118 league appearances for the Nottinghamshire side, scoring nine goals.
Cooper will reunite with the centre-back having had him in his squad during his time in Nottingham at the end of the 2016 season.
Hollis made his FGR debut in the 1-0 away defeat to Swindon Town in January 2018.
