EDEN PRAIRIE — Sam Bradford has begun his crash course in Minnesota’s offense.

Whether he’ll be able to learn enough in his first week for the Vikings to make him the quarterback in the season opener, well, that’s undetermined. Coach Mike Zimmer, naturally, wasn’t ready to declare a starter for Sunday. He didn’t rule out Bradford, either, with the game at Tennessee six days away.

“We’ll see how it goes,” Zimmer said.

Bradford took part in second practice with the team Monday, two days after the trade with Philadelphia that was triggered by the massive injury to Teddy Bridgewater’s left knee.

“Obviously it’s a little bit of an adjustment trying to not only learn a new system but adjust to the personnel and try to figure out how to throw to different guys,” Bradford said. “But it felt better today than it did yesterday, that’s for sure.”

The most reasonable timetable for the 2010 first overall draft pick to take over is probably the following week for the home game against Green Bay, with Shaun Hill playing this week. Immediate action for Bradford is certainly possible, though. With only two quarterbacks on the active roster, if Hill were to start and get hurt, Bradford would have to play regardless of his readiness.
