Cowboys Sign Versatile OL Matt Hennessy to Bolster Interior Depth

The move adds interior-line flexibility after Dallas declined to tender restricted free agent Brock Hoffman.

Overview

  • ESPN's Todd Archer reported late Thursday that Dallas agreed to terms with former 49ers lineman Matt Hennessy.
  • The Cowboys did not disclose contract details for Hennessy.
  • Hennessy, a 2020 third-round pick, has appeared in 64 games with 24 starts across stints with Atlanta and San Francisco.
  • He played all 17 games for the 49ers in 2025, including both playoff contests, and made two starts.
  • The addition is viewed as a likely replacement for Brock Hoffman, who was not tendered as an RFA and says he remains a free agent after denying a reported deal with the Steelers.
