Collins and Lee are eligible to return to the active roster after missing three games.
Lee has a pelvis injury that kept him from practicing in training camp, while Collins is working his way back from a hip injury.
The Cowboys re-signed linebacker Justin March and cornerback C.J. Goodwin, according to Archer. The team cut March and Goodwin on Saturday in procedural moves.

Goodwin, 30, played all 16 games for the Cowboys in 2019 and three games in 2018. He played 24 defensive snaps and 339 on special teams.
Bryant has a knee injury.
