Cowboys WR Miles Austin practiced on Monday with the first team, displacing Patrick Crayton to the role of third receiver.
Receivers coach Ray Sherman declined to confirm the obvious fact that Austin and Roy Williams are now the starting receivers.
"Right now, we are going through practice," Sherman said. "We have to make that decision when it comes."
Williams returned to practice after missing all of the Chiefs game and crunch time of a loss to the Broncos with a rib injury.
Austin re-signed with the Cowboys as a restricted free agent, at the second-round tender level of $1.545 million. Absent a new labor agreement, he'll be a restricted free agent again in 2010.
