Running back Adrian Peterson, who played in a game Monday for the first time since the 2014 regular-season opener, rushed for 31 yards on only 10 carries and caught three passes for 21 yards against the 49ers. Peterson lined up by Teddy Bridgewater in the shotgun formation four times and was stationed behind the quarterback, the place he’s used to being in, six times. It appeared as if Peterson was tentative in his return, but Zimmer disagreed with that assessment. “I don’t think he looked tentative,” Zimmer said. “I think he was aggressive trying to get to the hole and maybe trying to get to it a little bit too fast at times.” Peterson also appeared lost at times in pass protection, but Zimmer said the veteran only missed one assignment. “He’s been working real hard at it,” Zimmer said. “He’s gotten a lot better, in my opinion, than what he was.”
