Former Featherstone prop Darrell Griffin has won his case for unfair dismissal against the club.
Griffin, 36, was sacked in January for a “serious breach of contract” which was allegedly playing a number of games for Morley rugby union club.
An RFL tribunal was held this week and he was cleared of gross misconduct, serious subordination and breaching his contract.
He had always maintained that the club had given him permission to play for Morley, where he has continued to play since.
The former England international will now seek a settlement for loss of earnings, according to the Yorkshire Evening Post.
A Featherstone club statement said: “The club and its legal representatives attended a Rugby Football League tribunal on Tuesday.
“The hearing was called by representatives of former Featherstone player Darrell Griffin, who parted company with the Rovers in January.
“A decision was made following the tribunal, though the club and its legal team are yet to receive evidence to support it.
“Once presented, Rovers officials will decide on their next course of action.
“Until this time the club will be making no further comment.”
Griffin has previously played for Wakefield, Huddersfield, Salford and Leeds.
