RB David Oku signs with Arkansas St.

JONESBORO, Ark. -- Former Tennessee tailback David Oku has signed with Arkansas State.

ASU coach Gus Malzahn announced the signing of the former standout from Midwest City, Okla., on Wednesday.

Sports information director Jerry Scott said Oku will have two years of eligibility remaining and can play immediately because he sat out the 2011 season.

Oku led Tennessee in kickoff returns and return yardage as a freshman and sophomore but announced plans to transfer in January 2011 after dropping on the Volunteers' depth chart at tailback.
