Tyron Smith exited practice on Wednesday, leaving the Dallas Cowboys breathless.

According to ESPN's Todd Archer, the tackle's left knee will likely need an MRI.

As a result of going down on a play without much contact, he left practice early.

It's unlikely Smith has suffered a serious setback despite the troubling development.

Smith reassured Archer without saying anything, guard Connor McGovern said.

"I can decipher his grunts after playing with him so long," McGovern said. "He's fine."

As Smith walked out of the team facility, Clarence Hill Jr. said he looked fine.

Cowboys fans hate it. In 2020, Smith missed all but two games due to a neck injury.

If Smith isn't ready to start, Dallas' offensive line could devolve into a major question mark.

The Cowboys released veteran tackle La'el Collins and signed guard Connor Williams.

The Cowboys must have Smith healthy and effective to repeat as NFC East champions.
