The Patriots worked out free agent DL Spencer Johnson on Thursday. It's Johnson's first action of free agency. The 31-year-old nine-year veteran appeared in 14 games for the Bills last season, registering 19 tackles and two sacks as a rotational player. The Patriots have a crowded front line.

Bills reserve DL Spencer Johnson is sidelined with an ankle injury, and has been ruled out for Week 5. Johnson appears to have a high-ankle sprain, and is week-to-week. Sent to the bench following Buffalo's acquisition of Mario Williams and Mark Anderson, Johnson has just four tackles and zero sacks through four games.
