The work outs come in response to Tony Romo's broken left clavicle, which he sustained in the third quarter of Dallas' 20–10 win over the Philadelphia Eagles on Sunday. Romo is expected to miss eight weeks due to the injury.
Johnson, an eight-year NFL veteran, was also released by the Jets just prior to the 2015 season, while Bethel-Thompson was released by the Dolphins during final cuts and subsequently signed to the team's practice squad.
With Romo injured, backup Brandon Weeden is now the only active quarterback on Dallas' roster.
Weeden is 5–16 in his career as an NFL starter.
