Set to resume practicing Friday
Harris (elbow) remained a spectator for Thursday's practice, but head coach Mike Tomlin said the running back will be back on the field for Friday's session, Brooke Pryor of ESPN.com reports.
Tomlin mentioned that how Harris fares in Friday's workout will be telling for the rookie's availability for Sunday's wild-card game in Kansas City. Harris proved supremely durable during the regular season, approaching each of the Steelers' 17 contests without an injury designation while finishing with a league-high 381 touches (307 carries, 74 catches). However, after injuring his elbow early in Pittsburgh's Week 18 win over Baltimore, Harris could be at risk of taking a questionable tag into the playoff opener if he's anything less than a full participant at Friday's practice.
