Alameda, Calif. ? Warren Sapp announced his retirement on Thursday, ending the career of one of the best defensive tackles to play in the NFL.

Sapp posted a two-word message on his Web site, www.qbkilla.com, announcing his intention: “I’M DONE!” He had told teammates and coaches his plans after the season finale Sunday against San Diego. Sapp told the Contra Costa Times earlier Thursday that he had called Raiders owner Al Davis to give him the official news.

Sapp, 35, was the quintessential “three technique” tackle during his 13-year career, lining up between the guard and tackle and splitting that gap. Few did it better than Sapp, who made seven Pro Bowls, won The Associated Press Defensive Player of the Year award in 1999, and was a key cog in Tampa Bay’s Super Bowl winning defense in the 2002 season.

“Every defensive tackle that’s drafted in the top five is supposed to be the next (me),” Sapp said earlier this season. “All of them have that tag. … I’ve played the game pretty well, so if I’m the standard by which (they’ll) be judged, that’s tough, because I’d like to relive that guy, too. He’s a bad boy. He’s dead now. I give you flashes of him every now and then but, nah, that guy was sick.”

After having 10 sacks in 2006, Sapp wasn’t as successful this season when he finished with only two. He also was part of a Raiders defense that struggled against the run, allowing a league-worst 4.8 yards per carry.

Sapp was no longer the every-down menace he was during his younger days in Tampa, but he could still pick his spots. In his final game against San Diego, Sapp shot through a gap and hit quarterback Philip Rivers’ forearm before he could hand the ball off to LaDainian Tomlinson, causing a fumble.

“You get a little older, you can see your weaknesses a little bit more and go about 45-50 plays now,” Sapp said late in the season. “But there’s still some good gas in the tank and I’m still able to make the plays.”

Sapp finished his career with 961â2 sacks, the 28th most since the NFL began keeping track of the statistic in 1982. What made that even more remarkable is that Sapp played primarily on the inside at tackle, where sacks are traditionally much harder to come by.
