Bulls' Kyle Briggs and Jamie Langley both miss out on Sunday's game against Wigan Warriors.

Stand-off Briggs damaged his posterior cruciate ligaments in the season opener against Leeds at Cardiff last week and will be missing for between four and six weeks, while Langley will miss a similar period with a shoulder injury.

Marc Herbert has still not recovered sufficiently from the hamstring strain that kept him out last week. Danny Addy and Tom Olbison are added to the Squad.

Bulls squad: Addy, Ainscough, Ah Van, Diskin, Elima, Hargreaves, Kearney, Kopczak, L'Estrange, Lynch, Olbison, Platt, Raynor, Royston, Scruton, Sibbit, Sykes, Walker, Whitehead.
