Cowboys make several WR moves

IRVING, Texas -- The Cowboys made several moves regarding their receivers corps Wednesday.

Here's the roundup:

*Kevin Ogletree was officially placed on injured reserve. He's scheduled to undergo surgery on his right big toe Thursday.

*Manny Johnson, a seventh-round pick out of Oklahoma in 2009, was promoted from the practice squad to replace Ogletree.

*The Cowboys filled the vacancy on the practice squad by signing Troy Bergeron, a former Arena League star who never played college football. Bergeron spent most of this season on the Falcons' practice squad.

*Teddy Williams, the former UT-San Antonio track star who signed with the Cowboys during training camp, has been moved from cornerback to wide receiver. Williams, who has been clocked as fast as 9.9 in the 100 meters, has been on the practice squad all season.
