Nine-time Super League champion Jamie Peacock is to come out of retirement to help Hull KR preserve their top-flight status.
Rovers sit fourth in the Qualifiers, putting them on course for a place in the Million Pound Game, but they will be hoping to force their way into the top three over the course of their remaining trio of fixtures.
Peacock, 38, who enjoyed a glittering career with Bradford Bulls and Leeds Rhinos before retiring at the end of last season, is head of rugby at Craven Park.
The club registered him as a player in case of an emergency and, with Rovers facing a mounting injury list, Peacock has begun training with the first team.
"I've been happily retired for almost a year now and bowing out in last season's Grand Final with the Rhinos was the perfect way to bring my career to an end, but the time has come for me to put my boots on again," he told the club's official website.
"Although my family don't quite understand it, this feels like the right decision and I'm looking forward to getting back out there as quickly as possible.
"Physically, it may take me some time to get back up to speed but I've been preparing as best I can and mentally I'm in a good place. I'm going to fully embrace the challenge and do all I can to help the team until the end of the season.
"I understand my decision will be a big talking point but as far as I'm concerned I'm just focusing on training as hard as I can and getting back out there on the field as quickly as possible.
"I know it won't be easy to just pick up where I left off after nearly 12 months out of the sport, but I'm determined to give it my best shot."
