PITTSBURGH -- Pittsburgh Steelers coach Mike Tomlin said right tackle Marcus Gilbert is not in danger of losing his starting job despite giving up four sacks through the first two weeks of the season.

“I’m not concerned about Marcus and his ability to rebound,” Tomlin said Tuesday at his weekly news conference. “I expect him to come back fighting like Rocky.”

The fourth-year veteran needs to summon up some Balboa-esque grit after getting pushed around by Ravens outside linebacker Elvis Dumervil last Thursday night.

Dumervil recorded both of the Ravens’ sacks in a 26-6 win over the Steelers, and he beat Gilbert badly on the second one. The 5-foot-11, 255-pound Dumervil bull rushed Gilbert and knocked the 6-6, 315-pounder on his back on the way to a sack of Steelers quarterback Ben Roethlisberger.

Tomlin gave credit to Dumervil, an accomplished pass rusher, but he also said Gilbert needs to play better.

“When I coached college football I used to say they have scholarships, too. I think the same applies to the National Football League,” Tomlin said in reference to Dumervil’s success against Gilbert.

The Steelers, however, are expecting more out of Gilbert after signing the former second-round draft pick to a five-year, $26.2 million contract last month.

Gilbert played well in camp and the preseason, never allowing Mike Adams to mount a serious challenge to his starting job. The Steelers need Gilbert to show that his struggles in the first two games of the regular season are an aberration.

“If you play 60-plus snaps and you give up two sacks, it’s a bad game,” Tomlin said. “That’s the nature of our business, and I’m sure as a tackle that’s a challenge [Gilbert] embraces.”
