Vikings' Frazier: Christian Ponder (concussion) only injury concern

Vikings head coach Leslie Frazier said quarterback Christian Ponder is the team's only injury concern after Sunday's win over the Bears. Ponder left the game with a concussion that he suffered just before halftime.

"We'll have to see how things go with him over the next few days with the NFL protocol regarding concussions," Frazier said.

Due to Ponder's injury, Frazier didn't announce the starting quarterback for Sunday's game against the Ravens. Matt Cassel replaced Ponder and went 20 of 33 for 243 yards with a touchdown and an interception.

"There's no reason at this point on Monday at 12:40 [p.m.] that we have to make a decision," Frazier said. "We can talk it through and do what's best. But Matt did a terrific job in relief yesterday afternoon leading our team to victory."

Frazier said Ponder missing practice time or meeting sessions because he hasn't passed the concussion tests could factor into the decision at quarterback. Frazier didn't rule out Josh Freeman if Ponder can't play Sunday.

Linebacker Chad Greenway left Sunday's game after aggravating a fractured wrist injury he's played with for over a month. Frazier doesn't expect Greenway to miss Sunday's game however and feels he'll be back on the field after a few days.
