Cowboys Place All-Pro Guard Tyler Smith on IR for Thumb Surgery

Key points

• Tyler Smith will undergo surgery for a nagging thumb injury and is expected to miss four to six weeks.
• T.J. Bass will replace Smith at left guard, having previously started 10 games over three seasons.
• The Cowboys secured Bass via a second-round restricted free agent tender this offseason.
• Smith is placed on injured reserve designated for return, with a potential earliest return in Week 5.
• The Cowboys face a challenging early schedule against strong defensive lines in the first four weeks.

Background

This injury marks the first major setback for the Cowboys during the 2026 season, following a training camp and preseason without significant injuries. The team had previously focused on defensive upgrades under new coordinator Christian Parker and quarterback decisions involving Dak Prescott and Joe Milton III. Smith’s absence highlights the importance of depth on the offensive line, a unit that has been a cornerstone of the team’s success since his arrival in 2022.

How outlets are covering it

NBC Sports and the Dallas Cowboys official site emphasize the team’s confidence in T.J. Bass, citing his prior starts and the strategic decision to retain him via a restricted free agent tender. The NFL.com article highlights Smith’s status as a three-time Pro Bowler and cornerstone of the offensive line, noting that the decision to operate was made to ensure he performs at a high level for the remainder of the season. All sources agree on the 4-6 week timeline and the placement of Smith on injured reserve, with no significant disagreement on the facts presented.

Why it matters

The absence of a key offensive lineman like Tyler Smith could impact the Cowboys' ability to protect the quarterback and sustain drives, especially against strong defensive lines early in the season. The performance of T.J. Bass in the starting role will be a critical indicator of the team's offensive line resilience and depth.

What to watch

The Cowboys will monitor Bass's performance in the first four weeks of the season. Smith’s return is expected no earlier than Week 5, pending a 21-day practice window. The team may also consider promoting Nick Leverett from the practice squad to fill the roster spot vacated by Smith.
