It started with a flip.

The first development concerning Tennessee on national signing day came Wednesday morning when three-star defensive tackle LeDarrius Cox signed with Mississippi. Cox had been committed to UT since April 4.

The prospect from McGill-Toolen Catholic in Mobile, Ala., had visited Tennessee, Auburn and Mississippi throughout January.

Cox boasts a powerful frame, and he's comfortable pushing around offensive linemen on the interior of the line. He earned first-team Class 7A all-state honors.

Tennessee signed three defensive tackles during the December signing period, softening the blow of Cox's decommitment.

Later Wednesday morning, five-star wide receiver George Pickens flipped his commitment from Auburn to Georgia. Pickens, from Hoover, Ala., was a Tennessee target.

Three-star defensive back Jammie Robinson chose South Carolina on Wednesday afternoon over Auburn, Kentucky and UT.
