Tyron Smith, the left tackle for the Dallas Cowboys, is expected to be out for several months after being diagnosed with a torn hamstring.

According to Charean Williams of Pro Football Talk, Smith left Wednesday's practice with a knee injury that was originally thought to be a knee injury.

Smith grabbed his knee after barely touching another player during practice. Trainers helped him leave the field.

McGovern said he got a nice, reassuring grunt from the man. I can decipher his grunts when I play next to him. I think he is fine.

Smith'sACL is intact after initial review, according to Archer.

Smith had an ankle injury that he had to deal with in joint practices with the Broncos.

The eight-time Pro Bowler had a long history of injuries and was often not a full participant in practices because of knee and ankle injuries.

Smith missed two games because of ankle issues.

He played in two games because of neck injuries. Since 2015, he has not played a full season.

While injuries have slowed him down, he's still one of the best left tackles in the league, having earned eight Pro Bowl selections over his 11-year career.

The Cowboys decided to part ways with veteran La'el Collins earlier this year. When the season starts, Josh Ball, Matt Waletzko, and Aviante Collins could be in line to see more playing time.

The regular season begins with a game between the Cowboys and the Bucs.
