Yanda played through the injury last season, missing just one regular-season game with an ankle injury against the Denver Broncos.
Ravens coach John Harbaugh, who didn't disclose the nature of the injury, anticipates that Yanda, a two-time Pro Bowl selection regarded as one of the toughest guards in the league, will return by training camp.
"We expect him back by camp to some degree," Harbaugh said. "Marshal Yanda has done a great job with the rehab. He's right on schedule, probably ahead of schedule."
