Hull Kingston Rovers have confirmed that prop Liam Watts has asked to be released early from his contract.
The 21-year-old was named Super League's 'Rookie of the Year' in 2010 but has struggled to hold down a starting place this season.
Coach Craig Sandercock has used him in nine of KR's 16 Super League games.
Hull FC and Wakefield are among clubs said to be interested in a player still regarded as one of the most promising forwards in the country.
In June 2011, the club suspended Watts and full-back Ben Cockayne for alleged breaches of club discipline.
In April this year Watts was officially told he had no case to answer, but in the meantime he has fallen down the pecking order at the East Hull Super League club.
A Rovers spokesman said Watts had been given permission to talk to other clubs.
