Miami Dolphins starting left tackle Terron Armstead had to be carted off the field during Thursday's practice after he reportedly sustained a right leg injury.

He reportedly fell to the ground during 11-on-11 drills, was slow to get up and couldn't put any weight on his right leg.

Armstead, 32, signed with the Dolphins this past season after nine years with the New Orleans Saints. He missed four games in 2022 for various injuries: Armstead didn't play in Week 6 because of a toe injury or in Week 13 with a pectoral strain and he also missed the final two regular season games. Armstead did play in the Dolphins' wildcard loss to the Buffalo Bills, though. He also endured hip and knee injuries throughout the year.

He underwent arthroscopic knee surgery this offseason and the Dolphins placed Armstead on the physically unable to perform list to start training camp before he was activated on July 31.

The severity of Armstead's injury is unknown, but his absence would be a major blow to the Dolphins' offense. Miami went 1-3 in the four games Armstead missed in 2022 only scored 11 points in the Week 18 win over the New York Jets.
