Profootballtalk.com reports Arrelious Benn will miss four weeks with a sprained MCL suffered in Friday's training camp practice. Benn is building a history of knee woes, as he also tore his left ACL in December of 2010. A former second-round pick, Benn has been an utter disappointment in Tampa, managing 55 receptions and five touchdowns through two seasons, starting 23. He was a rotational player in 2011, unable to hold off Dezmon Briscoe for every-down snaps. With a new coaching staff in town, Benn can't afford to miss significant practice reps. He's on the roster bubble.
