With only youngsters Josh Ollerenshaw and Josh Bell in reserve, and neither of them on the subs bench, Crossley had to play on in considerable pain.
Manager John Sheridan confessed, "It's not quite clear what he's done. His thigh is either tight or he's pulled the muscle which is unfortunate, but we're lucky he could stay on the pitch. Thankfully we've now got a bit of a break so we can see how he is."
Backup keeper Les Pogliacomi is still ruled out until Christmas following his knee surgery so it might mean that Sheridan will be forced to bring in more cover, possibly on loan. He went on, "I'd have loved to have brought someone in as soon as Les got injured, but circumstances dictate otherwise. We'll have to have a look at Mark and see how he is. If the injury is serious then I will have to get someone in."
