BOSTON (CBS) — Patriots cornerback Stephon Gilmore suffered a lower-body injury during Sunday’s game against the Dolphins.

On a third down play, Gilmore fell to the turf mid-play and remained there throughout the play. After the 14-yard connection from Tua Tagovailoa to Lynn Bowden, trainers came out to tend to Gilmore, and they immediately paid attention to his lower leg. A replay showed that Gilmore slipped on the turf and awkwardly bent his left knee while trying to stop and change direction.

Gilmore left the game and was taken to the blue medical tent on the sideline. After an evaluation, he was helped to the locker room, without putting any weight on his leg.

The Patriots announced that he was doubtful to return with a knee injury. Later in the game, he was downgraded to out.

The 30-year-old Gilmore is under contract for the 2021 season, but due to his contract restructuring for this season, he has widely been viewed as being in his last year in New England.

Gilmore missed three games this season due to a knee injury, and he was on the injury report this week for a hand injury.
