Open Extended ReactionsOXNARD, Calif. -- The Dallas Cowboys will be without cornerback Caelen Carson for four to six weeks after he suffered a hyperextended knee Sunday, sources told ESPN. Also, DaRon Bland missed about a week following the birth of his son, but he returned Monday. Carson, a fifth-round pick in 2024, started last year's season opener against the Cleveland Browns, but he was limited to six games after being placed on injured reserve. According to ESPN's Adam Schefter, the Cowboys have added Christian Matthew, who worked out for the team Monday. Matthew had been with the Baltimore Ravens, but he also played for new defensive coordinator Matt Eberflus with the Chicago Bears in 2023.
