Titans linebacker Colin McCarthy appears headed for season-ending surgery on his injured shoulder.

McCarthy suffered the injury in Saturday's preseason game against the Green Bay Packers, and initial tests indicated he needs surgery. The fourth-year pro is scheduled to get another opinion next week, however.

McCarthy, a captain in 2012, was a fourth-round draft pick of the Titans in 2011. He started 19 of 36 games in his first three seasons, including five starts last year when he replaced injured Moise Fokou. (McCarthy had lost the starting job to Fokou in training camp.)

Injuries have been a problem during his career, however. He was working with the second- and third-team defense in training camp.
