FAYETTEVILLE — Knile Davis’ roller coaster of a career at Arkansas is officially over.

Davis will enter the 2013 NFL Draft, he announced on Wednesday.

Former Arkansas All-American track star Mike Conley will serve as the running back’s agent. Davis will also begin training with Michael Johnson at MJ Performance in Dallas on Monday.

"Over the last few weeks, I’ve been very reflective in weighing my options," Davis said in a release. "However after careful counsel with my family and support system, I’ve made the decision to forego my final year of eligibility and enter the 2013 NFL Draft. I sincerely look forward to working towards realizing my ultimate goal of becoming an NFL running back of the highest caliber."

In his time at Arkansas, Davis suffered two broken ankles, but he also led all Southeastern Conference running backs in rushing in 2010, between the two injuries. He ultimately struggled to return to the form of his sophomore season after his second broken ankle at Arkansas and the third dating back to his high school days.

In 2010, Davis rushed for 1,322 yards to help the lead the Razorbacks to the Sugar Bowl. He rushed for 1,028 yards in just the final seven games after using an 82-yard rushing performance against Texas A&M and a 91-yard performance against the eventual national championship Auburn Tigers to phase Broderick Green out and become the lead back with Dennis Johnson injured.

Against Ole Miss, Davis received a then-career high 22 carries and made the most of it by rushing for 176 yards and three touchdowns. In the next six games, he rushed for 100 yards five times, including 150-plus yard performances in wins against Mississippi State and LSU to help extend the Razorbacks’ win streak to six games and land them in their first BCS bowl game.

The Missouri City, Texas native looked primed to make a run at the Doak Walker award and ESPN analyst Kirk Herbstreit even called Davis a Heisman Trophy candidate in 2011, but on August 11, he broke his ankle in practice and missed the entire season.

In 2012, Davis decided to forgo the NFL draft and returned to play for the Razorbacks. At a press conference in January, Davis and Tyler Wilson said they shared a desire to play with one another and make a run at a National Championship, but the backfield duo and the team had an overall disappointing season.

Davis finished his final season with 377 yards rushing and scored three total touchdowns, while averaging just 3.4 yards per carry.

Davis also dealt with a hamstring injury that kept him out of the Tulsa and South Carolina games.

"In my four years at the University of Arkansas I’ve had many more ups than downs. As a 17-year-old coming to campus, I truly didn’t know what to expect. But, with the help of the administration, staff, and my teammates, the experience has exceeded my expectation, in developing me both as a player and a man.

"What I will remember most over the past four years has been the patience, support, and overall concern the Razorback Nation has shown me and my family after each setback. I will forever be a Razorback and will strive to make them proud on the next level."
