Auburn's Marks decides to enter NFL draft

Auburn defensive lineman Sen'Derrick Marks said early Tuesday morning that he will enter the NFL draft, and announce it at a news conference later in the day.

Marks, a junior, said that he stands 6 foot 2 and recently weighed in at 302 pounds.

"I can play both defensive tackle and defensive end," Marks said. "I want to be a player like Albert Haynesworth in the NFL. I know it's going to take hard work and dedication, but I'm going to bring my hard hat every day. I know that now, it's not just a game. It's a job. And I'm ready for that."

Marks said Tommy Tuberville's departure from Auburn had nothing to do with his decision to leave. Marks said he had good discussions with new coach Gene Chizik, but is simply ready to leave school. Marks had 10½ tackles for loss, including two sacks this season and a forced fumble.

Marks said junior defensive lineman Antonio Coleman might be following him to the NFL. He said he was told that Coleman will hold his own new conference at his high school later in the week.
