FOXBOROUGH, Mass. (AP) -- Jimmy Garoppolo and Jacoby Brissett were both in uniform as the Patriots went back to the practice field on Tuesday.
Which one of them will be at quarterback when New England hosts Buffalo on Sunday remains a mystery at this point.
Garoppolo missed last week's game against Houston with a throwing shoulder injury that occurred during the second quarter of the New England's win over the Miami Dolphins on Sept. 18.
In his absence last week, Brissett, a third-round pick in this year's draft, successfully led New England (3-0) past the Houston Texans in his first career start, but sustained an apparent right thumb injury sometime during the second half.
