The Ravens are expected to place veteran wide receiver Brandon Stokley on injured reserve following a concussion against the Minnesota Vikings, according to a source.

Stokley got hurt in the fourth quarter of the Ravens' 29-26 loss to the Vikings when he was tackled on the sideline by Vikings linebacker Chad Greenway following a two-yard reception.

Stokley has a lengthy history of concussions.

"We’ll have to see how it shakes out," Ravens coach John Harbaugh said Monday. "Unfortunately, he’s had a number of those in his career, so it could be problematic for us. We’ll have to see in the next 24 hours or so."
