Tampa Bay Buccaneers starting cornerback Jamel Dean suffered a concussion in the first quarter of Sunday's game against the Houston Texans and has been ruled out for the remainder of the contest. Dean was covering Texans wide receiver Nico Collins on a slant route when he dove to tackle Collins and missed his feet, hitting the turf hard with his upper body. Zyon McCollum, a fifth-round draft pick, has been stepping in for Dean and Carlton Davis in previous games.
