Offensive lineman Cameron Jefferson was expected to arrive in Fayetteville on Saturday night.
Arkansas players are scheduled to officially report today for fall camp.
Jefferson, 6-6, 305 pounds, 5.0 seconds in the 40-yard dash, signed with Arkansas after transferring from UNLV and will have one year of eligibility. Jefferson was allowed to transfer with immediate eligibility because UNLV was penalized by the NCAA for having a low Academic Progress Rate.
Former Iowa Western Community College offensive lineman Sebastian Tretola, 6-4 1/2, 315, 4.9, is already on campus.
Tretola and Jefferson were the last members of the 2014 class to arrive on campus, and both are expected to begin practice with the team Monday.
