Tarvaris Jackson Suffers Scare at Vikings Training Camp

A knee injury suffered by Vikings quarterback Tarvaris Jackson Saturday is not believed to be serious.

After all the hype surrounding Brett Favre's potential unretirement, the Minnesota Vikings have been trying to get back to normal.

Part of that normalcy is a training camp competition for the starting quarterback position. Incumbent Tarvaris Jackson and newcomer Sage Rosenfels will battle it out through the preseason for the right to start the opener Sept. 13 in Cleveland. For Jackson, his chances at the gig were -- at least temporarily -- in serious danger during Saturday morning's workout in Mankato, Minn.

Jackson was working in an 11-on-11 drill during practice when his left leg was rolled up on by defensive lineman Letroy Guion.

The initial report on Jackson's knee injury -- according to Pro Football Talk -- was an MCL sprain. While a more serious issue could have knocked Jackson out for some time, it's believed that he only suffered a Grade 1 sprain.

In the end, this single injury doesn't appear to be enough to tilt the quarterback battle toward Rosenfels. We've just started camp, and the Vikings are still almost two weeks away from their preseason opener. However, what could hurt the fourth-year pro is an injury history that is starting to pile up.

Jackson has already suffered knee, groin and finger injuries, as well as a concussion. He's not the most reckless quarterback in the league, but he likes to get out of the pocket, and his athleticism and arm strength make him a more dangerous player when he does that.

It also opens him up to more hits, and that doesn't appear to be helping him much.

More should be known about Jackson's injury after a Saturday evening practice in Mankato.
