Hull's Republic of Ireland midfielder Stephen Hunt is set to undergo a foot operation to find out if he can play again this season.[LNB] The Irishman has been struggling with the problem since February and his presence has been sorely missed by the relegation-threatened Tigers.[LNB]Iain Dowie has decided to send Hunt for surgery to find out the extent of the injury with reports suggesting he may have played his last game of the season.[LNB]"He's got a sharp pain in his foot again and we need to have a look at it in an operation," Dowie told the Hull Daily Mail.[LNB]"If he needs a procedure then it's going to be a lot longer but if everything is fine and we can move on, it might not be that long.[LNB]"We should get a bit of clarity on Tuesday morning."[LNB]Meanwhile, Dowie has vowed to wield the axe for next weekend's trip to Birmingham after the humiliating 4-1 defeat to relegation rivals Burnley.[LNB]"There will be a few changes next week," added Dowie. "Where we are in the league, I cannot allow that to go by and say it is acceptable because it is not. [LNB]"My players should be embarrassed. What I want now is a display with cojones. [LNB]"I would rather go to Birmingham and be a lion for a day than a sheep for the rest of the season. [LNB]"I'll be looking closely round the dressing room on Monday and Tuesday. It won't happen looking down at your shoes or trying to hide in the corner. [LNB]"It's a massive task given the number of wins we've got all season but it can be done."
