The Vikings are as close to full strength as they've been all summer.

Cornerback Trae Waynes, left guard Alex Boone, strong safety Andrew Sendejo, left tackle Riley Reiff, receiver Laquon Treadwell, running back Latavius Murray and linebacker Kentrell Brothers all were back in pads and participated in all of practice after missing Friday night's 20-13 preseason loss at Seattle.

No. 3 quarterback Taylor Heinicke did not practice. But the Vikings still had a third quarterback after signing former Gopher Mitch Leidner.

Near the end of practice, defensive end Brian Robison limped slowly to the locker room with what appeared to be a right leg injury. Coach Mike Zimmer said he wasn't concerned by the injuries to Heinicke and Robison.

The Vikings don't play their third preseason game until a week from today when the 49ers visit U.S. Bank Stadium.
