Trevon Diggs was released by the Dallas Cowboys because the team felt it was time to move on after a mix of performance issues, availability concerns, and off‑field/friction factors, not just one single incident.

Core reason for Diggs’ release

  • Multiple reporters have said the release was described inside the organization as a “culmination of events, including performance” , rather than one dramatic blow‑up.
  • After his big contract extension, Diggs’ play reportedly slipped from his All‑Pro peak, and the Cowboys no longer viewed him as a top‑tier cornerstone worth his scheduled cap hit.

Injuries and availability

  • Diggs missed large chunks of multiple seasons with serious knee issues, including a torn ACL and later procedures on the same knee, plus additional games for a right‑knee issue and a concussion from an at‑home accident.
  • Because of repeated rehabs and missed time, the team had growing concerns about his long‑term durability and how much they could rely on him week to week.

Team‑player and rehab tensions

  • Reports say the Cowboys were unhappy with how Diggs handled parts of his rehab, including choosing to work away from the team and missing enough of the voluntary offseason program that the club triggered a built‑in $500,000 salary de‑escalator.
  • Separate reporting has described friction over things like travel and scheduling, including a holiday situation where he wanted to stay with family instead of flying back with the team, which reportedly irritated coaches and leadership.

Money and cap considerations

  • Diggs was on a five‑year, roughly $97 million extension, but he no longer had guaranteed money left, which made it financially much easier for Dallas to cut ties.
  • By releasing him when they did, the Cowboys were projected to clear significant cap space for the following season (around the mid‑teens in millions), giving them flexibility for other roster moves.

What it was not mainly about

  • League insiders have stressed that his release was not primarily about the separate allegations involving his brother Stefon Diggs; those were widely discussed online but described as unrelated to the Cowboys’ internal decision on Trevon.
  • Instead, the picture painted by national reports is: declining performance post‑injury, availability and rehab frustrations, culture/”team‑first” questions, and a very expensive contract combining into one decision point.
