Gróf went on trial at West Bromwich Albion, but was released by Hibs towards the end of the 2008–09 season, despite having 18 months left on his contract. Following his release by Hibs, Gróf trained with English League Two side Gillingham, featuring in a reserve team match against Lewes.
Notts County
Gróf went on trial with League One club Notts County in July 2010. He agreed a deal to sign for the club, subject to medical.

Grof played an integral part in Mansfield's FA Trophy run which saw the Stags lose to Darlington in the final at Wembley on 7 May. Despite not being permitted to play in the final itself, Grof became a hero to the Mansfield fans due to his performances in both the FA Trophy and the Conference National, and appeared before the game against Darlington to a standing ovation from the 15000 strong travelling Mansfield fans. Despite rave reviews of his performances at Mansfield, Grof was waived by Notts County at the end of the season alongside defender Graeme Lee..
Walsall
Following a trial spell, Gróf signed a one-year contract with Football League One side Walsall in July 2011.
