The most recent Steelers starter to exit practice prematurely was third-year cornerback Artie Burns, who had his left leg/groin area wrapped Monday following the team’s first 11-on-11 session at Saint Vincent.

Notably, Coach Mike Tomlin said the injury was not serious. “Nothing significant there,” he said. “One of those day-to-day type of things.”

Four other starters did not practice Monday after sustaining injuries one day earlier. Those missing were safety Sean Davis (groin), outside linebacker T.J. Watt (hamstring), tight end Vance McDonald (foot) and wide receiver JuJu Smith-Schuster (undisclosed). Rookie linebacker Ola Adeniyi (undisclosed) also did not practice.

All of the injured players, with the exception of McDonald, were on the sideline watching practice.

Tomlin also confirmed guard Ramon Foster’s diagnosis as a hyperextension and bone bruise on his right knee, providing a four-week timetable for his return.

The coach said the team’s first day off from practice Tuesday comes at an opportune time. “It will give some of those guys with some minor injuries and day-to-day things an opportunity to get right and get back out there,” he said.

Tomlin is hoping some of the injured players can at least be partial participants when practice resumes Wednesday afternoon at Chuck Noll Field.

Veteran safety Morgan Burnett, who had missed three days of practice with hamstring tightness, did individual drills Monday but sat out the team activities.

“Don’t know the severity of any of these; such is life this time of year,” Tomlin said. “We will have more information on those guys when we get it.”
