"He will continue tests and evaluations before his medical team provides any further updates on his condition," the Steelers said in a statement. "We again want to thank the doctors and staff at UC Health's University of Cincinnati Medical Center for the excellent care Ryan received while at that facility."
Shazier was injured during Monday's 23-20 win versus Cincinnati while making a tackle on Bengals wide receiver Josh Malone with 11:14 remaining in the first quarter. The 25-year-old Shazier hit Malone low with his shoulder pads, then immediately reached for his back while his legs remained motionless.
The Steelers had hoped Shazier would be able to return to Pittsburgh on Tuesday. His transfer to the University of Pittsburgh Medical Center was pushed back as he remained at University of Cincinnati Medical Center under the care of neurosurgeons David Okonwko and Joseph Cheng.
Shazier tweeted out a message of gratitude to fans on Tuesday.
"Thank you for the prayers. Your support is uplifting to me and my family. SHALIEVE"
Shazier leads the team in tackles (89), interceptions (three) and pass deflections (11) this season.
