Arkansas moved into spreak break after wrapping up its third practice Thursday. But the practice field inside the Walker Pavilion won't be empty today. There's another group trying to impress. Arkansas players eligible for the 2012 NFL Draft will participate in a pro day workout on campus this afternoon. The group — which includes headliners like quarterback Tyler Wilson and running back Knile Davis — is scheduled to go through speed, agility and strength tests as well as other position-specific drills in preparation for April's draft.
