The Bills can place Gragg on IR if he passes through waivers, which we assume they might be up for since he was coming on strong before the nasty injury.
Gragg suffered a torn ACL during Friday's preseason loss at Washington, Vic Carucci of the Buffalo News reports.
One day removed from predicting the diagnosis, head coach Rex Ryan confirmed the news Saturday. With Gragg lost for the season, Blake Annen and Nick O'Leary may have clearer paths to spots on the 53-man roster.
The severity of Gragg's injury is currently unknown. Heading into Friday's contest, the 26-year-old projected as the third tight end on the Bills' depth chart.
Gragg caught two balls for 26 yards and a touchdown in Saturday's preseason loss to the Colts. He also blocked a punt for a safety.
Charles Clay is far and away the No. 1 tight end on this team, but it's wide open after that, with Jim Dray, Gragg, Blake Annen, NickO'Leary, and Jimmy Mundine all vying for what will likely be two spots. Gragg's performance Saturday will certainly help, especially when you consider special teams will probably be the tie-breaker. Dray is currently ahead of Gragg on the official depth chart, while Annen, who's just behind Gragg, is coming off a good camp.
