Minnesota Vikings running back Adrian Peterson participated in his first full pads practice since December 22nd yesterday. That was just two days before Peterson tore the ACL and MCL in his left knee on the first play of the second half in Minnesota’s 33-26 win over the Washington Redskins last season. On Tuesday, Peterson participated in just a handful of plays during 7-on-7 and full-team drills. Head coach Leslie Frazier says the team will still take an extremely cautious approach with their All-Pro running back. The Vikings host Buffalo in their second preseason contest on Friday. Coverage begins at 6pm, kick off at 7pm on SAM 107.3.
