Steelers Injury Report: Roethlisberger out, Shazier and McCullers day-to-day

The Pittsburgh Steelers and Baltimore Ravens are working with a short week as both teams prepare for a Thursday Night Football battle with significant AFC-North divisional implications on the line. For the Steelers, this meant head coach Mike Tomlin addressed the media on Monday rather than his usual Tuesday conference. During this time, Tomlin addressed several key injuries the Steelers are facing heading into their Week-4 matchup.

The news on Ben Roethlisberger had been well documented through social media on Sunday night and through a statement released by Tomlin via the organization early on Monday morning. Tomlin confirmed that Roethlisberger indeed suffered a sprained MCL ligament in his left knee, but would not speculate on any timetable for his return. Rather, Tomlin will wait until after the upcoming game on Thursday when he meets with his medical staff to get a feel for when Roethlisberger could possibly return to the field.

In other injury news, ILB Ryan Shazier (shoulder) and NT Daniel McCullers (knee) are continuing to work their way back to health, but each will be evaluated with a day-to-day approach by the Steelers. Tomlin said Shazier is experiencing weakness in his shoulder and won't return until he regains his strength in the joint.  Tomlin also said the team is taking a wait-and-see approach to CB Cortez Allen's injury (knee) as he looks to return to the field in the coming weeks.

The Steelers suffered two in-game injuries in their victory over the St. Louis Rams on Sunday. James Harrison injured his thumb, but Tomlin didn't think it would hinder his availability this Thursday night. Matt Spaeth fractured his hand and is being fitted for a cast. As his primary job on the team is serving as a blocking tight end, there's hope that Spaeth won't miss any time.

The Steelers (2-1) will host the Baltimore Ravens (0-3) on Thursday Night Football for their first divisional game of the 2015 season.
