LATROBE, Pa. -- Steelers running back James Conner has a sprained right AC joint and won't miss significant time.
Conner underwent medical testing after suffering an injury during Sunday's practice, during which he acquitted himself well with physical play.
"It appears to be minor - days," Steelers coach Mike Tomlin said.
Conner, currently the league's top-selling rookie of NFL-approved merchandise, was a third-round pick in April's draft and captivated college football as a Hodgkin's Lymphoma survivor while playing for Pitt.
Conner, Fitz Toussaint and Knile Davis are the Steelers' top running backs while the team waits for Le'Veon Bell, who's working out in South Florida and hasn't signed his $12.
