Minnesota Vikings quarterback Tarvaris Jackson suffered an MCL sprain in his left knee during Saturday’s practice, according to a person close to the situation.

This comes almost a year after Jackson sustained a sprained MCL in his right knee in a preseason game at Baltimore. Jackson missed the final two preseason games before returning for the first game of the season.

The extent of Jackson’s injury will be key because its significant impact on the battle for the starting  job between he and the newly acquired Sage Rosenfels.

Both Jackson and Rosenfels have been splitting the reps with the first team in the early part of training camp. Rosenfels said on the idea of splitting reps,“It’s not the premier situation you’d like to have,” Rosenfels said. “You’d like to be throwing with Bobby [Wade] and Bernard [Berrian] and [Visanthe Shiancoe] and all those guys. Every throw. But that’s not what we’re going to do.”

Jackson did have an MRI and is considered day-to-day.

With this injury, the Vikings may be looking at some familiar faces as an insurance policy. Like former Vikings quarterback Brooks Bollinger, who’s rumored to be going to UFL and former Virginia Tech Hokie Sean Glennon, who the Vikings waived in June after signing him as a rookie free agent.
