Texas A&M offensive tackle Luke Joeckel announced Tuesday that he's entering the NFL draft.

"This was a very difficult decision for me," Joeckel said on the school's website. "I have thought long and hard and visited with my family and coaches. I feel it is in my best interest to come out. I appreciate all that Texas A&M has done for me and my family. It is tough to leave a great group of coaches and players, including my twin brother, Matt. I know they will have a great season in 2013 and I will remain their biggest fan."

Joeckel is ranked as the No. 4 overall player by ESPN's Scouts Inc. The 6-foot-6, 306-pounder has quick feet, balance and aggressiveness, according to Scouts.

Texas A&M's other outstanding offensive tackle, Jake Matthews, has been seriously considering returning for another season, according to sources.
