Steelers coach Mike Tomlin confirmed that Conner remained in concussion protocol on Tuesday afternoon, but told reporters that the 23-year-old's participation in Wednesday's practice will "lay those discussions (about his availability) to bed."
Conner was evaluated in the sideline medical tent during the third quarter of Thursday's 52-14 romp over the Carolina Panthers. He briefly returned to the contest in the fourth quarter before retreating to the sideline.
The 6-foot-1, 233-yard Conner had another solid night before exiting the contest, rushing for 65 yards and a touchdown on 13 carries and adding one reception for eight yards.
With Le'Veon Bell away from the team this season, Conner has recorded a franchise-best 1,158 scrimmage yards (771 rushing, 387 receiving) in nine games. He also has 11 total touchdowns (10 rushing, one receiving).
A third-round pick out of Pitt in the 2017 NFL Draft, Conner has scored eight touchdowns (seven rushing) during Pittsburgh's five-game winning streak -- a span in which the Steelers have amassed 177 points.
The Steelers (6-2-1) bid to extend their winning streak on Sunday (1 .p.m. ET) when they visit the Jacksonville Jaguars (3-6) in a rematch of last season's AFC divisional-round game.
