NEW YORK — The NFL confirmed it is reviewing whether the Seattle Seahawks followed proper concussion protocol with quarterback Russell Wilson.

An NFL spokesman said Friday that the league is conducting a "thorough review" of whether the Seahawks followed the protocols when Wilson was sent off the field in the third quarter of Seattle's 22-16 win over Arizona.

Wilson was hit in the chin Thursday night by Karlos Dansby, who was flagged for roughing the passer. Referee Walt Anderson sent Wilson off the field. But Wilson was in Seattle's injury tent for only a few moments and he missed just one play.

Wilson said after the game, "I wasn't concussed or anything like that."

The team can be subject to league discipline if concussion protocols are not followed properly.

Wilson threw two touchdown passes to Jimmy Graham and the Seahawks (6-3) limited Adrian Peterson to 29 yards in 21 carries in a game marred by a host of injuries and penalties, most of them against Seattle.

Seattle's Kam Chancellor forced a fumble by Peterson on Arizona's first offensive play and later tackled him in the end zone for a safety.

At least seven players left the game with injuries, including Seattle cornerback Richard Sherman, who limped off the field in the third quarter with what was later reported to be a torn Achilles tendon, ending his season.

Wilson, sacked a season-high five times, completed 22 of 32 passes for 238 yards.

The night's biggest play came early in the fourth quarter. With his team leading 15-10, Wilson scrambled and spun his way out of serious trouble repeatedly before throwing from his heels to Doug Baldwin. Antoine Bethea fell down trying to knock the pass away and Baldwin raced downfield on a 54-yard play to the Arizona 2-yard line.

Wilson threw 2 yards to Graham on the next play and the Seahawks led 22-10 with 12:49 to play.
