The New England Patriots issued a statement on Sunday that defensive tackle Christian Barmore has been diagnosed with blood clots.

The team said he is being treated at Mass General Brigham and there is no timetable for a return.

Barmore, who turned 25 years old on Sunday, is coming off a career year, emerging as an anchor on New England's defensive front with a team-high 8 1/2 sacks while also recording 13 tackles for loss in 2023.

A second-round pick by New England in 2021, he totalled four sacks in his first two NFL seasons.

After his breakout 2023 season, the Patriots rewarded Barmore with a four-year contract extension worth up to $92 million on April 29.

"While there is no current timetable for his return, we know Christian is getting tremendous care and we look forward to his full recovery," the Patriots said in a statement.
