The 26-year-old was taken off just seven minutes into the second half of the Tigers' opening day clash with QPR having dislocated his kneecap
Hull City winger Robert Snodgrass is set to be sidelined for up to six months with a dislocated knee cap.
The Scotland international - signed for a reported £7 million from Norwich City during the summer - was forced from the field seven minutes into the second half of Hull's Premier League opener against QPR on Saturday.
Hull won that match 1-0, but manager Steve Bruce expressed concern that Snodgrass could be braced for a lengthy spell in the treatment room.
And those fears were confirmed on Wednesday, with Bruce revealing Snodgrass would require surgery on the joint and describing the situation as a "tragedy".
"We've lost Robert Snodgrass and the diagnosis is he'll be gone for six months, which is a big blow to us," the Hull boss told reporters.
"We spent a lot of money adding to our midfield area and now we've lost Snodgrass for the best part of the season. It's a tragedy for him and for us."
Snodgrass himself tweeted: "Gutted ....!!! But I will work as hard as I can to come back fitter and stronger."
Hull visit Lokeren for the first leg of their Europa League play-off on Thursday.
