Garoppolo will start Sunday against the Bills, WEEI reports.
After playing very well in the first game and a half of the season, Garoppolo suffered an injury to his throwing shoulder during the Week Two game against the Dolphins and sat out Week Three against the Texans. Jacoby Brissett started against Houston but suffered an injury of his own, to his throwing thumb.
Both Garoppolo and Brissett are officially listed as questionable for the game and have at least taken part in practice to some extent, reports have said. This is an early game, so owners should at least have a little better idea of the situation about an hour and a half before the start.
