Hull defender Michael Dawson is only expected to return to action after the New Year due to the hamstring injury he sustained against Chelsea on Saturday.
The 31-year-old limped off after just 10 minutes of the Tigers’ 2-0 defeat at Stamford Bridge, having already missed a month of the campaign with an ankle problem.
Scans showed the 31-year-old suffered a grade two tear during last weekend’s 2-0 Premier League defeat by Chelsea.
Dawson, who has captained the side twice in the absence of Curtis Davies, has already missed a month this season with an ankle injury.
Steve Bruce’s struggling side have dropped to second bottom in recent weeks and must play Swansea, Sunderland, Leicester and Everton in quick succession before an FA Cup third-round tie against Arsenal at the Emirates.
The crucial trip to West Bromwich Albion, on January 10, would be the quickest Dawson could return to City’s first-team plans.
“Unfortunately it’s a grade two tear and it could be anything from three, four, five weeks minimum I’d have thought,” said Bruce.
“That’s happened too much to us from the first day of the season with Robert Snodgrass to Dawson, to Nikica Jelavic to Mohamed Diame… it’s been one thing after another in that department.
“We could do with a little more luck because we’ve had four or five with pretty ugly injuries and we could without it.”
Senegal midfielder Diame is also still out injured while Scotland winger Snodgrass (dislocated kneecap) is a longer-term absentee.
Tom Huddlestone, sent off against Chelsea, will begin his four-match ban against Swansea on Saturday.
