SANTA CLARA, Calif. - Receiver Michael Crabtree and right tackle Anthony Davis did not practice Wednesday, which was made official by the 49ers' first injury report of the season ahead of Sunday's opener.
Crabtree is dealing with an apparent calf injury, while Davis is working through a hamstring.
Both the starting receiver and lineman were seen working out in the weight room adjacent to the team's practice field during the team's padded afternoon session.
Crabtree missed more than two weeks of training camp with a hamstring injury, which might be less of a concern than his calf after tearing his right Achilles tendon in OTAs last season causing him to miss 11 games. However, it is unknown which calf is injured.
Davis underwent offseason shoulder surgery to repair an injury he played through that occurred early in the season. He missed all of the team's offseason program and most of training camp before returning to practice prior to the team's third preseason game. His status for Sunday's season opener against the Dallas Cowboys is up in the air. Jonathan Martin replaced Davis at right tackle in the preseason.
Crabtree, entering a contract year, said he's 15-pounds lighter coming into the season after his Achilles injury prevented him from getting in ideal shape in 2013. But even without being at full speed, he managed 34 receptions for 487 yards in eight games, including the postseason.
For the Cowboys:
Did not participate: DE Anthony Spencer (knee), T Darrion Weems (shoulder)
Limited: DT Terrell McClain (ankle), DE George Selvie (Shoulder)
Full Participation: QB Tony Romo (back)
