Thorne was kicked in training and is now seeing a specialist.
City are reduced to three first team strikers with Robert Earnshaw, Andy Campbell and Gavin Gordon all on tour.
Gordon is the natural replacement for Thorne in the current squad. Gordon came on as a sub against Koge on Saturday but has been left completely out of the squad for tonights game according the the official team line up.
***Update 1900 hrs, Gordon would appear to be on the bench***
Earnie and Campbell start again as the front pairing against BK Frem of Copenhagen.
