Spencer sits out, Leary works with starters

IRVING, Texas -- Defensive end Anthony Spencer's return to practice appears to be delayed for at least another day.

Spencer, who has not practiced since undergoing arthroscopic knee surgery on July 25, worked out in the Valley Ranch weight room during the portion of Wednesday’s practice that was open to the media. The Cowboys continue to hope that Spencer will be available for at least a limited role in Sunday night’s season opener against the New York Giants.

Ronald Leary, who returned from arthroscopic knee surgery to be a limited participant in Monday’s practice, was working as the left guard with the first-team offense Wednesday. Mackenzy Bernadeau was playing right guard with Doug Free at right tackle with the starters.

Brian Waters, the six-time Pro Bowl guard who signed Tuesday night, played right guard with the second-team offense. Head coach Jason Garrett hasn’t ruled out Waters being active Sunday night, but Waters isn’t expected to make his starting debut for the Cowboys until Week 2 at the earliest.

Special-teams ace Danny McCray (hamstring) and running back Lance Dunbar (foot) did not practice and are considered doubtful for the season opener.
