Rookie linebacker Alex Anzalone was flagged for a personal foul for a helmet-to-helmet hit on Vikings running back Dalvin Cook on Monday, a bang-bang play that was difficult for 

Minnesota was setting up a screen, Anzalone had to fight off a block and he had just regained his balance after the trip when he made contact with Cook, who'd already dropped the ball.

Anzalone isn't sure there's anything else he could have done on the play. 

"I don't think so, but we'll see what happens," Anzalone said. "I got tripped from behind, so it kind of put myself in a tough position. I thought it was holding at first, the flag."

Veteran linebacker A.J. Klein told the rookie not to dwell on the 15-yard penalty, which helped the Vikings to a field goal. 

"Personally I didn’t think it was flagrant," Klein said. "The o-lineman that tried to cut him grabbed his legs as he was going forward, and I just told him to move on to the next play.'

Anzalone made two tackles and broke up a pass in 48 snaps against the Vikings. 

"I thought it was a tough call, tough decision," Saints coach Sean Payton said. "It’d be hard for them to say anything different, but I think the player is doing well.”
