All-Big 12 defensive end Stansly Maponga tweeted that he will forego his senior year and enter into the NFL draft.

The junior from Carrollton, Texas suffered from a foot injury in October against Baylor and elected to delay surgery until the offseason. He missed the Texas Tech and Oklahoma State games due to the injury and was marked as a day-to-day injury decision for the remainder of the regular season.

He had 22 tackles, including six for a loss, along with 2.5 sacks and two forced fumbles this past season. In 2011, Maponga was selected as an first-team All-Mountain West selection following a season with 55 tackles, nine sacks and five forced fumbles. 

Maponga is projected to be a fourth to fifth round draft pick. 

Maponga is the second Horned Frog to announce his early departure. On Jan. 8, receiver Josh Boyce announced he would enter into the draft.

Boyce enrolled early at TCU in spring 2009 and earned his degree in December, but had one year of eligibility remaining. He and Maponga are first TCU Horned Frogs to leave early for the NFL draft since Cory Rodgers in 2005.

All-America cornerback Jason Verrett was another underclassman rumored to leave for the draft, but announced on Jan. 6 he will stay TCU for his senior year. The cornerback from Fairfield, Calif., led the nation in passes defended (22) and led the Big 12 in interceptions (6).
