Buffalo Bills center Eric Wood believes that the Cleveland Browns' defense showed no "class" after his side's quarterback EJ Manuel was knocked out of the game.

Manuel took a hit in the fourth quarter of his side's game with the Browns which forced him to leave the match and was replaced with backup Jeff Tuel.

Tuel threw a costly interception late in the contest, which was returned for a touchdown by TJ Ward to win the game for Rob Chudzinksi's side.

"The hit was fine," Wood told ESPN.com. "What ticked me off was the way [the Browns] acted afterwards.

"I hope our defense never acts that way when they injure an opposing quarterback. You have to show some class in that situation."

The Bills are 2-3 in their season following their defeat in week five.
