Bryant signed with the Commanders on Tuesday.
The Cowboys signed Bryant to their practice squad in November, shortly after he was reinstated from an NFL suspension. He then signed a futures contract in January, only to be released in May before the start of offseason practices. The 32-year-old wideout last played in a regular-season game in 2018, making him unlikely to earn a significant role in Washington even though the team has a need at wide receiver behind No. 1 target Terry McLaurin.
