Tigers sign centre Ryan Shaw on a month's loan from Warrington
Castleford have summoned full-back Richard Owen to an internal disciplinary hearing.
Owen, 21, who has been handed the number one jersey by new coach Ian Millward for 2012, will face club officials on Wednesday.
"Castleford Tigers have called an internal hearing to address disciplinary issues relating to first-team player Richard Owen," the club said in a Tuesday statement.
"The hearing will take place tomorrow with club officials, the player and his agent.
"No further comment will be made until the matter is resolved."
Meanwhile, the Tigers have signed 19-year-old centre Ryan Shaw on a month's loan from Warrington. He represented England at Under 18 level but has yet to make his Super League debut for the Wolves.
A Warrington spokesman said: "All at the club would like to wish Ryan the best of luck for his time with the Tigers."
