Houston Texans defensive end Antonio Smith has revealed that he feels a lot "smarter" after being banned for the first game of the season.

Smith missed his side's win over the San Diego Chargers after he was suspended by the NFL after fighting with Miami Dolphins offensive lineman Richie Incognito in pre-season.

"I used to be a caged animal," Smith told the Houston Chronicle. "Now I'm a precision assassin. I'm a lot smarter now [after the suspension]."

Houston face the Tennessee Titans on Sunday.
