EAST RUTHERFORD, N.J. (AP) -Seven-time Pro Bowl defensive end Michael Strahan is retiring after a 15-year career, capped by a Super Bowl title with the New York Giants in February.

The 36-year-old Strahan, the NFL's active leader in sacks, informed the Giants on Monday.

``I'm just finding out about it; let me get organized,'' coach Tom Coughlin said after a team offseason workout.

Strahan's retirement first was reported by Foxsports.com

``It was important that my teammates knew which way I was going before they got on the field to start the work to defend our title,'' Strahan told the Web site. ``It's time. I'm done.''

Strahan had hinted at retirement last season and missed almost all of training camp while coming to a decision to play.

He returned days before the season, anchoring a defensive line that was instrumental in hounding New England quarterback Tom Brady in New York's stunning Super Bowl victory over the previously unbeaten Patriots.
