Brissett (right thumb) was officially listed as a limited practice participant Wednesday.
Both Brissett, who is dealing with a sprained thumb on his right (throwing) hand, and Jimmy Garoppolo (sprained right AC joint), were able to throw some Wednesday, though neither player would reveal the team's starting QB plans for Sunday's game against the Bills. "That's Coach [Bill Belichick]'s decision," Brissett declared Wednesday. "I can't make that decision."
