Dallas Cowboys star wide receiver CeeDee Lamb didn’t practice with the team Wednesday due to an ankle injury, the team announced in their injury report.

Specifics on his ankle injury are not known. Lamb was one of several key Cowboys players held out of practice Wednesday, too, along with defensive tackle Mazi Smith and cornerback Trevon Diggs.

According to ESPN’s Todd Archer, the Cowboys expect both Lamb and Diggs to be available for Sunday’s game against the Baltimore Ravens. Smith’s status for that matchup is unknown.

It’s unclear when or how Lamb injured his ankle, or how severe the injury is. The 25-year-old, who struck a new four-year, $136 million extension with the Cowboys after holding out during training camp, had four catches for 90 yards and a touchdown in their 44-19 loss to the New Orleans Saints on Sunday. He was targeted seven times in that loss, and all four of his catches came in the first half.

Diggs was held out of practice on Wednesday due to a foot injury, though specifics were unavailable. Diggs, who returned this season from a torn ACL he sustained early last year, had five total tackles in Sunday’s loss.

Smith was seen walking off the practice field early on Wednesday with a back injury, which could be another blow to an already depleted defensive line. The Cowboys placed defensive tackle Jordan Phillips on injured reserve Wednesday. Phillips first sustained a wrist injury last season while playing against the Cowboys when he was with the Buffalo Bills, which led to surgery. It’s unknown if he will need surgery again this fall, but he will be out for at least four games.

The Cowboys will host the Ravens on Sunday afternoon. Baltimore, after falling to the Las Vegas Raiders in what was a second straight major survivor pool upset, is attempting to avoid what would be just the second 0-3 start in franchise history.
