JuJu Smith-Schuster landed on the Steelers' injury report Thursday after suffering a groin injury in practice.
For a Steelers team already dealing with an injury to running back James Conner, this is potentially a big blow as Pittsburgh is striving for a playoff berth as it tackles the NFC South champion New Orleans Saintson the road Sunday.
Smith-Schuster, a 22-year-old second-year wideout, is having a stellar campaign as he leads the AFC with 95 catches and his 1,274 yards receiving are sixth in the NFL. He also has six touchdown catches and is coming off a win against New England in which he hauled in four catches for 40 yards.
The Steelers' final practice of the week is Friday. Should Smith-Schuster miss Sunday's game, it's likely James Washington would step into the starting role opposite of Antonio Brown.
