Mark Sanchez will start at quarterback in the New York Jets' exhibition opener Friday at the Detroit Lions.
Coach Rex Ryan made the announcement Tuesday.
Sanchez and rookie Geno Smith were listed on the team's latest depth chart as co-starters.
"Mark will start the game," Ryan said. "But we'll play Geno with the ones as well. And we'll keep that rotation going so they'll both get reps with the ones. Haven't really decided yet what the play time with the ones will be or snaps and all that."
Sanchez received boos during the team's scrimmage on Saturday. Despite that, Ryan said the competition between Sanchez and Smith has been a draw.
"It's been an even competition," Ryan said. "We've got rotating days and things like that. Certainly (Mark's) the incumbent. We'll see how it goes from here. It seemed like the natural thing to do."
