UPDATE: The Vikings have downgraded Rhodes to out for the rest of the game with a concussion.
Philip Rivers found Keenan Allen for a 34-yard touchdown pass near the end of the half. Xavier Rhodes was in coverage on Allen, and as he attempted to bring Allen down after the catch, he collided with safety Andrew Sendejo. Rhodes went to the turf in a heap, and laid on the turf for a while before eventually getting up and walking to the locker room under his own power.
The Vikings are saying that Rhodes is being evaluated for a head injury, and that his return to today's game is questionable. Given the mini-controversy that came out over the course of this week with guard Brandon Fusco, you can be sure that the Vikings will be extra careful with Rhodes on this one.
If Rhodes can't come back, it's likely going to be a trial by fire for rookie Trae Waynes, who has not played a defensive snap yet this season. The Vikings deactivated cornerback Jabari Price for this one, and the only other option would appear to be throwing special teams ace Marcus Sherels out there at corner. We'll see what the Vikings elect to do right away, as the Chargers will get the ball to start the second half.
Again, Vikings' cornerback Xavier Rhodes is being evaluated for a concussion, and his return to the game is questionable.
