Brissett completed all nine of his pass attempts for 85 yards and a TD in Friday's preseason win over the Panthers.
Jimmy Garoppolo started the game and wasn't especially sharp against Carolina's first-team defense. In contrast, Brissett -- who ran three times for six yards -- put up a tidy stat line, albeit against reserves. With Tom Brady on track to sit out the Patriots' first four games of the regular season, Brissett is slated to serve as Garoppolo's backup out of the gate in 2016.
