Renfrow was a limited participant at practice Wednesday with hamstring and ribs injuries, Rachel Gossen of the Raiders' official site reports.
Renfrow wasn't included on the Raiders' Week 9 injury report, but the slot man -- who was on the field for 44 of a possible 59 snaps on offense in this past Sunday's loss to the Jaguars -- is now nursing a pair of injury issues ahead of this weekend's game against the Colts. He now has two more chances to practice fully before the Raiders' final Week 10 injury report is posted Friday.
