Bennett was taken to a hospital, but the Texans announced that he has feelings in all his extremities.
Bennett was in the Texans' backfield trying to make a sack when he was sandwiched between several other players and went down face-first on the field.
Players stood close by and looked concerned as medical personnel attended to Bennent, who moved his head and one arm as he was leaving the field and speaking to Seattle cornerback Brandon Browner.
Bennett is in his fifth NFL season out of Texas A&M. This was a hometown game for Bennett, who grew up in the Houston suburb of Alief. The Seahawks signed him to a one-year, $4.8 million deal as a free agent in the offseason after playing four years for Tampa Bay.
