Trayvon Mullen has been officially waived by the Dallas Cowboys ahead of their trip to face the San Francisco 49ers in the NFC Divisional Round.

Mullen was claimed off of waivers in December and active in just one game, struggling to make an impact for a CB unit in need of assistance. The team has since signed Xavier Rhodes, who has been elevated on Saturday for a second time, leaving one elevation available for Rhodes from the practice squad.

The vacant seat created by divorcing Mullen will be filled by offensive tackle Aviante Collins, who was signed to the active roster today after losing Jason Peters to a hip injury.

Brock Hoffman, a backup interior offensive lineman, joins Rhodes in being elevated from the practice squad.
