Mark Cooper's injury list is already causing problems, with new striker Chris Senior still a doubt for tomorrow's game with Carlisle United.

The Cumbrians come to the Northern Echo Arena on Friday night (7.30pm kick-off) for the third and final home friendly of a hectic pre-season programme.

Trinidad and Tobago international goalkeeper Kelvin Jack is still out with a slight hamstring strain, while Senior is about 50-50 for the game after suffering a dead leg against Sunderland last Saturday.

Striker Tommy Wright may be available for the game tomorrow after making good progress from a thigh strain he picked up against Sheffield Wednesday on Tuesday night.

Midfielder Gary Smith continues his rehabilitation after an ankle clear-out operation in the summer and is hoping to return to full training next week, while Gareth Waite is also going through rehab following knee surgery earlier this year and is hoping to return to training by the end of the month.

Young midfielder Corey Barnes is available again after recovering from a back injury.
