Colin McCarthy has been a defensive team captain for the Titans, he has also been injury prone throughout his four years in the NFL and with the Titans.
The former Miami Hurricane star suffered yet another setback Saturday night in the Titans preseason opener against the Green Bay Packers when he suffered a shoulder injury.
The severity of McCarthy's injury is unknown at this point, and just how long he might be on the shelf is as equally unknown.
According the head coach Ken Whisnehunt during his Sunday press conference, McCarthy, and guard Chris Spencer, who was also injured in Saturday's game are still being evaluated, and will throughout the coming week.
"They've been checked out today," said Whisenhunt. "But we'll know more as the week progresses.
The injury and lost practice time are not the only, or potentially biggest thing the former defensive captain stands to lose with his latest injury.
Currently mired on the third unit of linebackers, and in a battle for a roster spot, an injury and missing practice time and possibly a preseason game could mean the end of McCarthy's time in Tennessee.
For McCarthy, the best hope it to miss a day or possibly two of practice, because if this injury is a longer term issue it will be extremely hard for him to remain on the roster.
