The Dallas Cowboys have signed a new offensive lineman, Chris Glaser, in response to the injury concerns surrounding Matt Hennessy's neck surgery. Glaser, who played for the Columbus Aviators in the UFL, had a brief stint with the Cowboys in 2023 and was undrafted in 2022. He will compete with Tyler Guyton and Nate Thomas for the starting role. The competition is expected to heat up during training camp, where the defense will be able to test the linemen's skills. Coach Brian Schottenheimer has stated that the team wants to see consistent performance from the players before making a decision. The Cowboys are looking for a true battle for the position, and Glaser's addition adds to the excitement. The team is giving the players a chance to showcase their skills over three practices, and the competition is expected to be fierce. The outcome of the competition will be decided during training camp.
