Source: Patriots set to activate DT Barmore

FOXBOROUGH, Mass. -- New England Patriots defensive tackle Christian Barmore will be activated to the 53-man roster Saturday, setting the stage for him to return to action for the first time since being sidelined in late July after being diagnosed with blood clots, a source confirmed to ESPN.

Barmore practiced for the first time Thursday, with coach Jerod Mayo saying there was a chance Barmore could play in a limited role in Sunday's home game against the Los Angeles Rams if cleared by doctors.

"We will see what he can handle and build from there," Mayo said.

To make room for Barmore on the roster, the Patriots are waiving receiver Tyquan Thornton, a source told ESPN's Adam Schefter.

Thornton, a 2022 second-round pick out of Baylor with blazing speed, never emerged as the top threat the Patriots had hoped he would.

Barmore, 25, is viewed as one of the team's cornerstone players. In April, he signed a four-year contract extension with a maximum value of $92 million, including $41.8 million in guaranteed money.

After Barmore had participated in the first practice of training camp, the team announced he had been diagnosed with blood clots and treated at Mass General Brigham, saying there was no timetable for his return.

Barmore has remained around the team, helping behind the scenes, while also working with other injured and rehabilitating players.

The 6-foot-5, 315-pound Barmore has played in 44 regular-season games (11 starts), totaling 133 tackles,12.5 sacks and 9 pass deflections.
