Two defenders flip from UAB

Defensive end Kalvin Robinson (Vestavia Hills, Ala./Vestavia Hills) and cornerback Jamaris Hart (Florence, Ala./Florence) are no longer committed to Alabama-Birmingham and have pledged elsewhere, multiple sources report.

Robinson is now committed to Western Kentucky. He posted the following on Twitter: "Let me reintroduce myself: Good day to all, my name is Kalvin Robinson and I'm a WKU commit."

Hart has flipped to Arkansas State, the back-to-back Sun Belt champions.

UAB now has 22 commitments for the Class of 2013, as they also lost four-star athlete T.J. Green (Sylacauga, Ala./Sylacauga) to Clemson yesterday.
