YORK City Knights prop David Bates could be doubtful for Sunday's crunch clash against Gateshead.

The Ireland international lasted no more than five minutes in the heat against Swinton on July 10 after limping off with a leg problem that has now been diagnosed as a hamstring attachment injury.

He is undergoing treatment but it may not be enough to get him fit enough for an intense match against the in-form Thunder.

Head coach Mick Cook said: "It's a bit early to say at the moment. He and Neil Law are responding to treatment but progress is still a little bit sluggish. It's only a few days since he played but he could be doubtful."

Lee Jackson is back in training after his dead leg, and Austin Buchanan is also looking strong.
