HOUSTON (AP) -- Houston coach Gary Kubiak says the NFL has upheld defensive end Antonio Smith s three-game suspension.
Smith was suspended Wednesday for the last two preseason games and Houston s season opener for hitting Miami guard Richie Incognito with the Dolphins player s helmet.
Smith appealed the suspension, but his appeal was denied Friday. Kubiak says he s disappointed in the decision, but that the team understands and accepts it.
Smith ripped the helmet off Incognito s head, then hit Incognito on the shoulder with it Saturday night in the teams preseason game.
The two also went at it in last season s opener, when Smith kicked Incognito, drawing an $11,000 fine. Smith later said Incognito deliberately tried to twist his ankle while holding his legs in the 2012 game.
