Mike Tomlin joined his quarterback in expressing disappointment in the playing surface at Acrisure Stadium for the Pittsburgh Steelers’ game Sunday against the Cleveland Browns.

A day after Aaron Rodgers said the grass surface was “borderline unplayable,” Tomlin said the conditions were “poor.”

Kicker Chris Boswell slipped on a 54-yard field goal attempt, and the surface may have contributed to special teams captain Miles Killebrew sustaining a knee injury that Tomlin again called “significant.”

The Steelers don’t play again at Acrisure Stadium until Oct. 26 against the Green Bay Packers. A day earlier, Pitt plays N.C. State at the venue.

“I’m not concerned going forward because my understanding is that turf is going to be swapped out,” Tomlin said. “I certainly acknowledge it was a concern yesterday.”

Grounds crew members already were replacing parts of the sod immediately after the Steelers’ 23-9 victory against the Browns.

The Steelers had not played on their North Shore home surface since Sept. 14 in their home opener against Seattle. Tomlin was unaware of the conditions of the stadium’s grass surface.

“I don’t work over there,” Tomlin said. “I work over here” at the UPMC Rooney Sports Complex on the South Side.

Tomlin said he had “no idea” if the unstable grass field contributed to Killebrew’s injury. Killebrew was removed from the sideline on a cart.

Although the Steelers haven’t announced the severity of Killebrew’s injury, Tomlin said the Steelers will be without him Thursday when they play the Cincinnati Bengals at Paycor Stadium. Killebrew is in his fourth season serving as the team’s special teams captain. A renowned punt blocker, Killebrew is tied for third on the team with five special teams tackles.

“We can hurt for him as a man, as a teammate, as a brother and as an individual,” Tomlin said. “From a football perspective, one man’s misfortune is another man’s opportunity. We certainly have some capable people, and there is an expectation that others step up and fill in the gaps.”

Tomlin isn’t yet ruling out wide receiver Calvin Austin returning from his shoulder injury that caused him to miss the game against the Browns. The Steelers have one official day of practice before their game against the Bengals.

“We’ll see what this week looks like,” Tomlin said. “We do have a good work day tomorrow. We’ll see what that holds.”

Tomlin was encouraged by the way cornerbacks Jalen Ramsey and Joey Porter Jr. played in their return from hamstring injuries. Outside linebacker Alex Highsmith also returned from a high ankle sprain.

“There were bumps and bruises, but nothing that would raise our antennas regarding play availability Thursday night,” Tomlin said.
