Dolphins third-string quarterback Tyler Thigpen likely will start Thursday night's game against the Chicago Bears after starter Chad Pennington and backup Chad Henne left Sunday's victory over the Tennessee Titans with injuries, a team source told NFL Network's Michael Lombardi.
Multiple sources are reporting that both quarterbacks could be finished for the season.
The Dolphins will almost certainly sign at least one quarterback from free agency or the practice squad to backup Thigpen. Former No. 1 pick Jamarcus Russell is among the names under consideration, the Miami Herald reports.
