Oklahoma defensive end Ronnell Lewis officially announced his intentions to skip his senior season and declare for the NFL draft on Thursday.
The 6-foot-2, 244-pound Lewis was a second-team All-Big 12 selection by The Associated Press and is rated as the No. 4 outside linebacker by ESPN's Scouts Inc.
"Ronnell leaves with our best wishes," Oklahoma coach Bob Stoops in a statement Thursday. "He managed several challenges while playing here, but always worked hard and gave us his very best effort. He has the skill to be a successful NFL player and we feel he'll do well there."
Lewis, a former 8-man football star at Dewar (Okla.) High School, flourished this season, his first as a full-time starter. He had 5.5 sacks and 13 tackles for loss
He missed the final three games of the season. He suffered a sprained MCL against Baylor and missed the following week's win over Iowa State. He was also suspended for the regular-season finale against Oklahoma State for missing classes and didn't play in the Sooners' Insight Bowl win over Iowa because of academic issues.
