Ravens starting safety Marcus Williams, left tackle Ronnie Stanley, and center Tyler Linderbaum all left Sunday's Ravens-Texans Week 1 opener with injuries and did not return.
Head Coach John Harbaugh said all three will be evaluated with MRIs to determine the severity of their injuries.
Williams went to the locker room late in the second quarter and was ruled out shortly after halftime with a shoulder injury. NFL Network's Ian Rapoport reports that Williams is feared to have torn his pectoral muscle.
Stanley and Linderbaum both went down in the fourth quarter and did not return. Linderbaum walked off and went to the locker room. Stanley remained on the sideline and his injury does not seem serious, per The Athletic's Dianna Russini.
Geno Stone, who was already getting snaps when the Ravens showed a three-safety look, joined safety Kyle Hamilton on Baltimore's back end for the rest of the game.
Williams missed seven games with a dislocated wrist last season and losing him again for a significant period would be a blow to the defense. He's a natural playmaker with a knack for forcing turnovers and led the Ravens with four interceptions last season despite his injury. He covers ground and often deters quarterbacks from throwing deep against the Ravens, and he's also a strong run defender who had four tackles Sunday before leaving the game.
Linderbaum started every game for the Ravens last season as a rookie. Stanley has dealt with injuries the past several years and was finally healthy to start the season for the first time since 2020.
"It's football, and everyone just does the best they can, and we certainly did and certainly will continue to," Harbaugh said. "I'm sure there's injuries around the league."
