The Jaguars got their first win of the season yesterday, but they didn’t get to celebrate for long.

Via Ryan O’Halloran of the Florida Times-Union, veteran middle linebacker Paul Posluszny suffered a torn pectoral muscle yesterday and will be out for the year.

That’s a huge blow for a young team that was beginning to show signs of life after an 0-6 start, taking the leader out of the middle of the defense.

“It’s a big loss,” Jaguars coach Gus Bradley said. “That will be a difficult one.”

Posluszny will have surgery this week, and will be placed on injured reserve.

Bradley also said that defensive end Andre Branch suffered a groin injury, and would miss about six weeks.
