Cleveland Browns quarterback Tyrod Taylor was ruled out for the second half of Thursday night's game against the New York Jets after he suffered a concussion in the second quarter.
The 29-year-old was 4-of-14 passing for 19 yards before exiting.
No. 1 overall pick Baker Mayfield entered in Taylor's place and made his professional debut shortly before halftime.
After going winless with DeShone Kizer and Kevin Hogan in 2017, Cleveland made the move to acquire Taylor in March to provide some relief to the franchise's seemingly endless quarterback carousel.
Last season, Taylor helped the Buffalo Bills end a 17-season playoff drought by leading them to a 9-7 record (8-6 in his 14 starts).
