Hull City manager Steve Bruce has confirmed that defender Paul McShane will undergo knee surgery on Monday.
The 28-year-old limped out of last Tuesday's 1-0 defeat to Southampton after colliding with Tigers goalkeeper Steve Harper.
"We knew it was a serious one when we saw the pictures, his ankle was practically the other way around, so Paul has an operation on Monday," explained Bruce.
"It's not broken but he's severed a couple of ligaments in there that need to be repaired. We don't know the real extent until the surgeon goes in, but I wouldn't have thought he'll play any more part in this season.
"I would have thought it will be about six months out, so maybe the best case scenario is to be fit for the start of next season."
McShane is under contract at Hull until June 2015.
