Ryan Fitzpatrick or Josh Rosen? 

That remains the question Miami Dolphins head coach Brian Flores is trying to answer with Week 1 of the regular season on the horizon. On Tuesday, Flores said that the Dolphins have not decided on a starting quarterback for their season-opening game against the Baltimore Ravens, per Adam Beasley of the Miami Herald. 

When it comes to Miami's preseason finale Thursday against the New Orleans Saints, Flores said that there's a chance that Fitzpatrick, who is currently ill and was doubtful for Tuesday afternoon's practice, will sit. Rosen, who started Miami's second preseason game against the Tampa Bay Buccaneers, will likely get his second preseason start Thursday night. 

Fitzpatrick and Rosen alternated starts during the first three weeks of the preseason. 

Both quarterbacks put forth impressive drives during the second half of the team's most recent preseason game, a 22-7 victory over the Jacksonville Jaguars. Fitzpatrick, who started the game, engineered an 85-yard scoring drive on the first possession of the second half that culminated with his eight-yard touchdown pass to Mark Walton. 

Rosen, who replaced Fitzpatrick on the ensuing possession, orchestrated a 13-play, 99-yard drive that saw him complete all but one of his five pass attempts. He also scrambled twice for 25 yards while also connecting with Isaiah Ford for 39 yards to help set up Patrick Laird's five-yard touchdown run.
