Shazier injured his knee in the team's Week 3 win over the Carolina Panthers, and despite MRI results not showing torn ligaments, he's still expected to be out at least until Week 6 with the injury - categorized as a sprain.
"We’ll get him moving and get an evaluation," Tomlin said. "I wouldn’t be too optimistic about his participation."
He did note everyone else, including left guard Ramon Foster but excluding cornerback Ike Taylor, is expected to be back in practice this week. Taylor will be out for several weeks with a broken arm. Foster missed the team's last two games, and has been replaced during that time by Cody Wallace.
The Steelers' defense was up and down in the loss to the previously winless Buccaneers, and it appears as if they'll play their second game in a row missing three starters from their Week 1 lineup. Jarvis Jones is out for another seven weeks at least with a wrist injury. He was placed on the IR-Recall list. The Steelers appear content with the team they have at present and, after replacing Jones's spot on the roster with veteran James Harrison, they haven't made any further roster moves.
William Gay assumed Taylor's starting spot against Tampa Bay and Brice McCain filled in at nickel back.
