Childress not concerned about Jackson

Brad Childress expressed little concern about the knee injury suffered by quarterback Tarvaris Jackson on Saturday.

Childress, speaking after the Vikings’ second practice of the day, would not confirm that Jackson suffered a Grade 1 sprain of the medial collateral ligament in his left knee during the morning session, but the Vikings coach said he has no plans to bring in a third quarterback to take reps behind Sage Rosenfels and John david Booty. That should serve as a clear indication that Jackson won’t be out long because if he was going to miss substantial time someone would need to be signed to take some of the reps.

“I’ll have to see going forward,” Childress said when asked about Jackson’s status. “I’m not that clairvoyant. He just stayed and treated and it looks like he’ll be just fine.”

Jackson was injured during an 11-on-11 drill when he stepped up in the pocket and collided with defensive tackle Letroy Guion, who had slipped to the ground while being blocked by center John Sullivan.
