A quick look at the biggest injury-related news concerning this Vikings roster at the moment:

PERCY HARVIN:  The Vikings dynamic playmaker only played in nine games before suffering an ankle injury that sidelined him for the remainder of 2012, as they officially placed him on injured reserve on December 5th.  On Sunday Harvin tweeted that he would be having “minor surgery” and it was initially assumed he was talking about his ankle.  Instead, however, Leslie Frazier indicated that Harvin instead had to undergo emergency appendectomy surgery.

When it comes to Percy Harvin, things are never crystal clear, but it does appear that he has no intentions of playing next season without getting a new contract.  His ankle injury (not the appendectomy) only muddies those waters and the Vikings could be in for an ugly fight and some think we may have seen Harvin play his last game as a Viking.

CHRIS COOK:  When Chris Cook suffered a broken arm on October 25th the Vikings had let only two receivers top 100 yards in eight games.  Those two receivers, Donnie Avery and Andre Roberts, were not Cook’s assignment for the day.  They have had much more trouble since then, giving up a pair of monstrous games to Calvin Johnson (207 yards) and Brandon Marshall (160 yards).

Cook is eligible to return next week, just in time to finish the season against Andre Johnson and Greg Jennings, but there is no guarantee that he will.  Leslie Frazier said that the team will be monitoring Cook’s conditioning and make a decision later on in the week.

BRIAN ROBISON:  On Sunday, defensive end Brian Robison made an immediate impact by sacking Sam Bradford early on.  Then, he had to leave the game with a shoulder injury.  Robison is expected to have an MRI done and Frazier said he will probably be day-to-day this week.

Luckily for the Vikings, they have impressive depth at Robison’s position, and Everson Griffen was a more than sufficient replacement on Sunday.

OTHERS:  Count Adrian Peterson and Marcus Sherels among the Vikings that came out of Sunday’s game with some dings and bruises.  Still, nobody other than Cook and Robison are considered to be very questionable for this week’s trip to Houston.
