Minnesota Vikings quarterback Christian Ponder left Sunday's win over the Chicago Bears with a concussion, Ben Goessling of ESPN.com reports.
Ponder was injured on a helmet-to-helmet hit just before the end of the first half. He wasn't very effective before the injury, completing just three of his eight passes for a mere 40 yards.
Under Matt Cassel, the Vikings rallied back from a ten-point deficit to beat the Bears 23-20 in overtime. Coach Leslie Frazier didn't have an update on Ponder after the game. "We'll sit down on Monday and talk about where we are and figure out where Christian is, health-wise, over the course of the week," he said.
Cassel completed 20 of 33 passes for 243 yards and a touchdown after replacing Ponder. When asked if Ponder would be considered to start next week, Frazier said "Of course. He'd have to be in consideration, for sure."
Whichever quarterback gets the start Sunday will face a Baltimore defense that ranks 12th overall defending the pass and 6th against the run. The game will kick off at 1 PM.
