BBAO: Already a major Packers injury

We're Black and Blue All Over:

The Green Bay Packers lost a promising rookie -- perhaps for the season -- on the first day of their organized team activities (OTAs), according to multiple reports. Offensive lineman J.C. Tretter, a fourth-round draft pick who was being trained at multiple positions, broke his ankle and tore ligaments during Monday's opening OTA. His agent believes he will miss six months.

Monday's practice was closed to the media but reporters noted that Tretter was not in attendance Tuesday. Packers coach Mike McCarthy did not comment on the nature of the injury, but agent Alan Herman told Jason Wilde of ESPNMilwaukee.com and Tyler Dunne of the Milwaukee Journal Sentinel that the injury occurred when his foot got stuck in the turf while sliding during a fumble recovery drill.

Tretter didn't figure as starter or even a key backup in 2013, but if nothing else the Packers will lose valuable development time with a long-term prospect. It's also an auspicious start to spring practices a few months after McCarthy said the team was working to explain why it has been beset by so many injuries in recent years. You figure Tretter will open training camp on the physically unable to perform (PUP) list and it's possible he will miss the entire season.
