PITTSBURGH (AP) — Pittsburgh Steelers Pro Bowl linebacker Ryan Shazier attended practice on Wednesday for the first time since injuring his spine against Cincinnati last month.

Shazier posted a photo on Instagram on Wednesday afternoon from the team’s indoor training facility as Pittsburgh prepared to host Jacksonville in the divisional round of the playoffs. Shazier, who underwent spine stabilization surgery on Dec. 6, is pictured in a wheelchair wearing sweatpants and a Steelers jacket.

The extent of Shazier’s injury has not been released. He called his visit to the facility “a first down” in his recovery. Shazier says he has been “making strides” over the past month but added he is “far from done.” The 25-year-old Shazier says he is “working harder than ever” to get back.

The Steelers host the Jaguars on Sunday and the winner will advance to the AFC title game.
