Alabama running back Mark Ingram and defensive end Marcell Dareus will announce at a news conference Friday that they plan to enter the NFL Draft, according to sources. Razorbacks wide receiver Julio Jones is likely to follow, though sources added that he hasn't yet made a final decision. Ingram is No. 22 on RealGM senior football writer Jeff Risdon's most recent prospect ranking list. Dareus (13) and Jones (18) are also near the top of Risdon's list.
