Mandatory Credit: Lucas Boland-USA TODAY Sports The Dallas Cowboys made two roster moves Wednesday as they prepared for Monday night’s game against the Las Vegas Raiders. The club placed safety Juanyeh Thomas on the reserve/non‑football illness list and signed offensive tackle Marcellus Johnson to the practice squad. Thomas will miss at least four games as he addresses an ongoing migraine issue, the team announced. The safety had appeared in seven games this season and his absence forces Dalas to lean on other members of the secondary while he seeks treatment and recovery.

Johnson’s addition gives the team insurance in case of an injury to a starter or backup during the short week ahead of the matchup against Las Vegas. https://www.youtube.com/embed/H43g2lRMaRA?feature=oembed Coaches described the moves as routine roster management during a long season that requires flexibility. The club lost Geron Christian from the Cowboys’ practice squad earlier this week when he signed with another team, creating an immediate need at tackle. Johnson’s familiarity with practice‑squad life and previous work in league systems made him an efficient pickup for Dallas.
