Renfrow (concussion) was a full participant in Wednesday's practice.
The Raiders haven't yet announced that Renfrow has been removed from the league's five-step concussion protocol, but at the very least, the slot man looks to be trending in the right direction for Saturday's game against the Dolphins. Before exiting early with the head injury in the Raiders' Week 15 loss to the Chargers, Renfrow caught one of his two targets for a four-yard gain across 13 offensive snaps.
