Miami Dolphins quarterback Tua Tagovailoa has a small fracture in the middle finger of his left, throwing hand and will not start Sunday against the Houston Texans, league sources told ESPN.
Jacoby Brissett is expected to be the Dolphins' starting quarterback Sunday, according to a source, with Tagovailoa serving as Miami's backup.
Tagovailoa was limited with his throws all week and has made progress, but his finger has not healed to the point where he can start against Houston.
He likely will play only in an emergency situation Sunday, according to sources, but is expected to dress as the backup because the Dolphins are short-handed at the position, after quarterback Reid Sinnett recently was claimed off waivers by the Philadelphia Eagles.
