NFL Free Agency
The NFL's free-agent frenzy officially is under way, and ESPN.com will keep you updated with all the twists and turns of the signing period.
Avril received the Lions' franchise tender last offseason and didn't sign his one-year, $10.6 million contract until a week after training camp began.
Avril, who will turn 27 on April 8, finished last season with 9.5 sacks, 35 tackles and two forced fumbles.
One of the premier pass rushers on the free-agent market, Avril has 39.5 career sacks and 16 forced fumbles since 2008, when Detroit drafted him out of Purdue in the third round.
