The Patriots secondary has had a rough week.
On Monday, it allowed three touchdown passes and 10.5 yards per pass attempt to Joe Flacco, needing a JC Jackson interception in the fourth quarter to spark a comeback.
On Thursday, it was missing three players at the team's practice despite having all players present for a walkthrough on Wednesday.
Stephon Gilmore (knee) practiced twice last week and was listed as "questionable" for Monday's game before eventually being ruled out. His presence on the field Wednesday indicated that he was progressing toward a return. But he was among the missing Thursday.
