With Tom Brady sidelined for Thursday's preseason win over the Bears, Brissett took over at QB early in the third quarter of the contest, NESN.com reports.
Working mostly with the team's second-unit, Brissett completed 9-of-13 passes for 87 yards and ran once for five yards. With Brady set to sit out the Patriots' first four games of the regular season, Brissett remains on track to serve as Jimmy Garoppolo's backup out of the gate, given that the team has opted not to add a veteran backup to this point in time.
