Vikings QB Jackson leaves field after collision with defensive lineman

Vikes QB Jackson hurt during scrimmage

MANKATO, Minn. — Minnesota Vikings quarterback Tarvaris Jackson left the field on Saturday morning with an apparent leg injury.

Jackson was injured during a team scrimmage when defensive lineman LeTroy Guion fell at his feet and rolled over his leg. Jackson crumbled to the field in pain as trainers rushed to his side. After a few minutes, he was able to get up and walk off under his own power.

There was no immediate word on the nature of his injury.

Jackson is in a battle with Sage Rosenfels for the starting quarterback position after Brett Favre decided not to come out of retirement and join the Vikings.
