Josh Freeman still isn't sure exactly which third-quarter hit caused his first NFL concussion on Monday night, and he didn't say whether he will return to the Minnesota Vikings' starting quarterback role next week. But when his next opportunity does come, Freeman believes he'll be better than he was during an erratic performance in his Vikings debut. Freeman was cleared to practice on Friday, and coach Leslie Frazier said the Vikings plan to return him to full practice next week. He will be inactive on Sunday, with Christian Ponder starting at quarterback and Matt Cassel backing up Ponder against the Green Bay Packers, but the Vikings' plan for their quarterbacks after that remains unknown.
