Former Cowboys CB Trevon Diggs Lands Tryout With Detroit Lions

Former Dallas Cowboys cornerback Trevon Diggs has landed a tryout with the Detroit Lions, according to reporting from Sporting News on August 10, 2026. The move marks a shift for the former All-Pro defender following a reported messy exit from the Cowboys organization.

Diggs, who established himself as one of the league’s premier ball-hawks during his tenure in Dallas, is now seeking a roster spot with a division rival in the NFC. The tryout indicates that the Lions are evaluating the cornerback’s current form and fit for their defensive secondary.

Trevon Diggs’ Transition from the Dallas Cowboys

The departure of Diggs from Dallas was characterized by Sporting News as a messy exit. While the specific details of the friction between the player and the Cowboys management were not disclosed in the report, the terminology suggests a breakdown in the relationship between the All-Pro cornerback and the team.

Diggs previously served as a cornerstone of the Dallas defense, earning All-Pro honors for his ability to generate turnovers. His departure leaves the Cowboys to find a replacement for his production in the secondary as they navigate their current roster construction.

Detroit Lions Evaluation and NFC Impact

By bringing in Diggs for a tryout, the Detroit Lions are targeting a veteran with a proven track record of high-level play. The Lions’ decision to evaluate a former star from a fellow NFC team provides them an opportunity to add experienced depth to their defensive backfield.

The outcome of the tryout will determine if Detroit offers Diggs a contract. If signed, Diggs would transition from one NFC contender to another, potentially facing his former teammates in Dallas during the regular season.

The move highlights the volatility of veteran cornerback positions in the NFL, where high-performing players can move from starter roles to tryout status following contractual or interpersonal disputes with their previous clubs.
