The Patriots are activating defensive tackle Christian Barmore from the non-football illness list on Saturday, according to a source.

Barmore is expected to play Sunday against the Rams despite practicing just once since July.

The 25-year-old defensive tackle was diagnosed with blood clots early in training camp. He began the season on the non-football illness list and missed the first 10 weeks of the season.

Barmore returned to practice Thursday. He didn’t participate in Friday’s practice since he must be limited from exertion in back-to-back days as he weans off of blood thinners.

Patriots head coach Jerod Mayo said Friday that there was a chance that Barmore could play this week. He also said “the expectation is there is no expectation” for Barmore as he recovers from a serious condition.

Barmore joins Davon Godchaux, Daniel Ekuale, Jeremiah Pharms, Jaquelin Roy and Eric Johnson on the Patriots’ defensive tackle depth chart.

The team released wide receiver Tyquan Thornton from the 53-man roster to make room for Barmore. The team also could activate cornerback Alex Austin from injured reserve, though they would have to open up another spot on the 53-man roster.

Barmore was one of the Patriots’ best defensive players last season, tallying 8.5 sacks, and was rewarded with a four-year, $84 million extension in April.
