Source: Patriots work out WR Collie

FOXBOROUGH, Mass. -- Free-agent wide receiver Austin Collie worked out for the Patriots, according to a league source.

The 27-year-old Collie has spent the last four seasons with the Indianapolis Colts. He was limited to one game last season because of a knee injury, and he’s also had at least three concussions.

Collie told USA Today that he would sign a waiver if a team was concerned about his health.

“They’re not going to have to worry about me suing,” Collie told Mike Garofolo in early June. “I’ll hold myself to be accountable. I just need that closure. When I feel like I accomplish everything I want to accomplish, I’ll have no problem walking away from the game. But I have more to give.”

The Patriots were noticeably thin at receiver during Tuesday’s practice, when rookie free agent Kenbrell Thompkins received repetitions with veteran Michael Jenkins and Danny Amendola in the top three-receiver set. An unidentified receiver, possibly on a tryout, was also at practice.

Collie has 173 career receptions in 42 regular-season games (16 starts), totaling 1,845 yards and 16 touchdowns.
