Jerry Jones Reveals Cowboys’ All-Pro Has Knee Tendinitis as Injuries Mount originally appeared on Athlon Sports.

Injuries are starting to threaten the Dallas Cowboys’ preparation ahead of a pivotal 2025 season, and another blow hit the offense on Thursday.

The most recent man to go down is All-Pro guard Tyler Smith, who left Thursday’s training camp practice in Oxnard, California, with a knee issue.

Cowboys owner and GM Jerry Jones later confirmed that Smith is dealing with knee tendinitis, adding to the injury concerns facing an already depleted unit.

Smith left practice roughly 30 minutes before it ended, and the 23-year-old did not participate in team drills, walking to the locker room on his own.

Though Smith told reporters he felt “fine,” the Cowboys are not going to take any chances as injuries pile up across their offensive front.

Fortunately for Dallas, the team scheduled a rest day on Friday, giving Smith at least one day off and nearly 48 hours of rest before the next scheduled session on Saturday.

Cowboys O-Line Facing Depth Crisis Before Preseason

The Cowboys’ offensive line has suffered a string of injuries in recent weeks.

• Left tackle Tyler Guyton fractured a bone in his knee and is expected to miss four to six weeks, casting doubt on his availability for Week 1.
• Right guard Rob Jones, who had seemingly climbed ahead of rookie Tyler Booker on the depth chart, suffered a neck fracture and will miss several months.
• Left tackle Hakeem Adeniji suffered a concussion during Thursday’s practice.
• Right tackle Terrence Steele suffered a high ankle sprain at the start of training camp but returned to practice after getting a low-grade sprain diagnosis.

Even with Steele back on the field, the mounting injuries have forced the team to experiment with different combinations on the offensive line at different times throughout the first week of training camp.

Brock Hoffman took first-team reps at left guard in Smith’s absence, while Nate Thomas and Asim Richards rotated at left tackle. Rookie Cooper Beebe lined up at center, and Booker filled in at right guard.

Cowboys Entering a Pivotal Year With Little Margin for Error

With Zack Martin retired and three linemen now sidelined, the protection of quarterback Dak Prescott is starting to become a concern for a team entering a high-pressure season.

Smith’s tendinitis may be minor, but the Cowboys’ offensive line is thin, and any extended absence of Smith or another lineman would further strain an already fragile unit.

Dallas is entering the season with Super Bowl aspirations and doesn’t have much more room for any type of injury setback.
