Michael Dawson is the latest blow to Steve Bruce's plans ahead of the festive fixtures after scans have revealed that the 31-year-old has torn his hamstring, reports the Daily Express.
The former Spurs defender joins the ever growing list of absentees along with Robert Snodgrass and Mo Diame ,whilst Tom Huddlestone begins his four match ban ahead of the visit from Swansea City on Saturday.
Dawson has been a key asset to the Hull defence, and their poor form overshadows how well the Englishman has performed this season.
His summer arrival cost Bruce a mere £3.5 million from the hands of Mauricio Pochettino and has been added to a strong set of defenders in East Yorkshire for the likes of Curtis Davies, Alex Bruce and James Chester.
But constant injuries and suspensions amongst the Tigers' back line have resulted unrest, thus explaining their turbulent form which has seen them win just twice all season.
Bruce confirmed on Thursday that: "It’s a grade-two tear like we thought, so that means it will be three to five weeks minimum, which unfortunately has happened to us too much."
"When you're without big players, you have to roll your sleeves up" he explained as his side prepare for a meaty affair with Swansea at the weekend in search of their first victory since October 1."
With several vital games approaching such as Leicester, Sunderland and Everton, Bruce revealed his disappointment to the lengthy absence of his captain.
“We've got three or four games coming up which will define our season. It's just how 2014 has gone for us and the sooner it is over the better. The Premier League is unforgiving. We're stretched to the limit at the moment, but we can't make that an excuse" he added.
