Minnesota Vikings' safety Andrew Sendejo's one-game suspension has been upheld for violating the NFL's player safety rules for a hit against the Baltimore Ravens' receiver Mike Wallace on Sunday.

He'll miss Sunday's game at the Cleveland Browns.

Wallace took a vicious hit to the head from Sendejo in the first quarter, which drew a 15-yard unsportsmanlike penalty.

Wallace was ruled out with a concussion and afterward, he was spotted on the sideline trying to find his helmet, searching in every equipment case. It had flown 15 yards from the spot of the hit.
