Pittsburgh Steelers linebacker Ryan Shazier reportedly showed "promising signs" Tuesday morning and has some movement in his lower extremities after suffering a back injury Monday night against the Cincinnati Bengals, according to NFL Network's Ian Rapoport.
Despite the positive news, Rapoport added that the next 24 to 48 hours are key for Shazier in terms of increased improvement.
Shazier exited during the first quarter of Monday's 23-20 win over the Bengals following a collision with Cincinnati wide receiver Josh Malone.
Per ESPN.com's Jeremy Fowler, Shazier was transported to the University of Cincinnati Medical Center on Monday, where he underwent an MRI and a CT scan.
