Vikings coach Leslie Frazier said the team hopes Christian Ponder is able to do more work in practice Thursday after being limited on Wednesday because of his rib injury.

Frazier said Ponder experienced "some soreness" on Wednesday which prevented him from doing as much work as the team had hoped. Matt Cassel took the majority of snaps.

"We’re going to try and give Christian more today to see if he can handle it and try and make a decision by Friday" Frazier said.

Frazier said the team likely will make a decision on Ponder after Friday's practice as opposed to a game-time decision.

"Probably if he couldn’t do anything on Friday to where we felt comfortable we probably wouldn’t put him out there if we didn’t see what we needed to see on Friday" Frazier said.

Ponder's injury raised speculation that the Vikings saw this as a convenient opportunity to make a quarterback switch. Frazier dismissed that conspiracy theory.

"It’s purely circumstantial if that happens" Frazier said. "We want Christian to play. We want him to get out there and continue to grow and develop as a quarterback. But we signed Matt Cassel for occasions just like this if something were to happen to Christian. We’ll see what happens."
