Peterson's health: For the Vikings, this is probably the issue: Running back Adrian Peterson will have a MRI on his sprained foot on Monday, and while he was optimistic about his prognosis on Sunday -- he said X-rays were negative, and added he would push to play Sunday against the Philadelphia Eagles -- Monday's tests might have the final say about whether Peterson plays again this season. He said the pain was in the middle of his foot, which would be in the region of the dreaded Lisfranc injury, and turf toe could also still be in play. We'll find out more after his exam on Monday.
Toby time? In Peterson's absence, running back Toby Gerhart continued to show what a capable replacement he can be, romping 41 yards for one of the Vikings' would-be game-winning touchdowns in the fourth quarter and posting 89 yards on 15 carries. It is the third time in four weeks that Gerhart has posted at least 60 yards, and it was the first time this season he has carried the ball more than 10 times in a game. He is averaging 6.2 yards per carry this season, and could be making a case for more of a shared workload in the final games of the season (though it will be hard to convince Peterson to carry the ball less, if he's healthy). Gerhart will be a free agent after the season, and it's looking increasingly likely that he's going to make himself some money.
Henderson marginalized: The Vikings moved Erin Henderson to outside linebacker this week, putting him back on the field after he'd missed the last two games in the wake of his Nov. 19 drunken-driving arrest and a subsequent personal issue that kept him away from the team for several days. But with Audie Cole starting at middle linebacker, and once again playing every snap, Henderson saw how little the Vikings use their third linebacker in their current defense. He played just six snaps in the loss, one more than Marvin Mitchell saw on defense. When Henderson was the Vikings' weakside linebacker last year, he still played in the middle in the nickel package, keeping his snap counts high. But without the nickel snaps, Henderson didn't get a chance to do much. Cole was in coverage on Marlon Brown's two big catches on the Ravens' last drive -- including his game-winning touchdown -- but the linebacker nearly tipped Joe Flacco's pass away before Brown could catch it in the back of the end zone, and coach Leslie Frazier credited Flacco for a good throw more than he pointed to a coverage breakdown.
Fines coming? Peterson was critical of both referees and Ravens fans after the game, pointing out a number of calls he disagreed with and calling the Ravens' fans the "worst in the NFL" after they were throwing snowballs on the field in the fourth quarter, and it stands to reason he might hear from the league this week. Fullback Jerome Felton was also critical of the referees, saying there were four questionable calls that all went against the Vikings, but other players were more diplomatic, particularly when discussing two dubious pass interference calls in the fourth quarter. "I'm not going to say anything to get on Roger Goodell's list," defensive end Brian Robison deadpanned.
