Lamb sustained a shoulder injury in Week 9 but has been playing through it. The wideout will now "undergo a process of treatment and rehabilitation for his shoulder," and is expected to "make a full recovery" without surgery, the team said. He will not appear in the final two games of the season.

The Dallas Cowboys have been ravaged by injuries this season. Dak Prescott was lost early in the season, and All-Pro guard Zack Martin suffered a season-ending injury weeks later.
