Entering Week 2, the Steelers remain shorthanded at guard. All-Pro David DeCastro will miss a second straight game, and Stefen Wisniewski looks likely to be out much longer.

The Steelers placed Wisniewski on IR Friday. He will not be able to return to action until at least Week 5. The 10th-year veteran interior lineman is sidelined with a pectoral injury. Wisniewski is expected to return at some point this season, with NFL.com’s Tom Pelissero noting the injury is not expected to require surgery (Twitter link).

Wisniewski signed with the Steelers earlier this offseason, doing so after working as a Chiefs starter in their three playoff games. The two-time Super Bowl starter was set to replace retired left guard Ramon Foster and started in Week 1. But the Steelers have been forced to make other plans at the position to start the Season. Fourth-round rookie Kevin Dotson is expected to replace him at guard against the Broncos, Mike Tomlin said.

Pittsburgh already lost right tackle Zach Banner, so the team will be down to just two O-line starters — center Maurkice Pouncey and left tackle Alejandro Villanueva — on Sunday. DeCastro is battling a knee injury.

The Steelers will also promote tackle Derwin Gray, a 2019 seventh-round pick, from the practice squad, the team announced.
