The Dallas Cowboys took another major step toward finalizing their roster during Tuesday's training camp practice in Oxnard, California. The biggest news came before practice when head coach Brian Schottenheimer officially named Tyler Guyton the team's starting left tackle, bringing one of the most important position battles of camp to an early conclusion.

The decision allows Tyler Smith to remain at left guard, giving Dallas continuity along the interior offensive line while entrusting Guyton with protecting Dak Prescott's blind side.

Tyler Guyton Earns the Job

Although Guyton sat out team drills Tuesday with a sore elbow, the coaching staff made it clear they believe he is the long-term answer at left tackle. His absence allowed Nate Thomas to receive the majority of the first-team reps, but the starting role now belongs to Guyton once he returns to full health.

Tempers Boil Over

Practice intensity reached another level when rookie edge rusher Donovan Ezeiruaku was ejected after getting into a heated altercation with offensive tackle Terence Steele.

Rather than allowing the fight to continue, Schottenheimer immediately sent Ezeiruaku off the field, reinforcing his emphasis on discipline throughout camp.

Tough Injury News

The Cowboys also received disappointing news regarding backup tight end Princeton Fant, who suffered a torn ACL and partial MCL during Monday's practice.

Fant will miss the entire 2026 season, reducing Dallas' depth behind starting tight end Jake Ferguson.

Injury Report

Several Cowboys were limited or unavailable during Tuesday's session:

  • Tyler Guyton: Sore elbow; missed team drills.
  • DeMarvion Overshown: Leg soreness.
  • Jonathan Bullard: Hamstring injury suffered during warmups.
  • Jalen Thompson: Hip flexor.
  • P.J. Locke: Knee injury.

The team expects Thompson and Locke to return in the near future.

Standout Performers

Dallas continued to see encouraging performances from several key players:

  • Marist Liufau forced and recovered a fumble during team drills, continuing an impressive camp.
  • Dak Prescott connected with Jake Ferguson on a perfectly thrown deep seam pass, highlighting the offense's growing rhythm.
  • Rookie defensive tackle Quinnen Williams remained one of the most disruptive defenders on the field, consistently winning one-on-one pass-rush drills and creating problems for the offensive line.

S³ Take

Naming Tyler Guyton the starting left tackle provides stability for Dallas' offensive line before the preseason begins. Keeping Tyler Smith at guard strengthens the interior while allowing Guyton to develop into the franchise's blindside protector.

The ejection of Donovan Ezeiruaku also reflects the competitive atmosphere inside Cowboys camp. Physicality is expected, but Schottenheimer appears determined to maintain discipline as the regular season approaches.

If Guyton returns healthy from his elbow soreness, the Cowboys may have settled their most important offensive position battle weeks before Week 1.
