Jets quarterback Mark Sanchez left Saturday night's preseason game early with an injury to his throwing shoulder.
After Geno Smith played most of the game--racking up three interceptions and a safety--Sanchez entered in the 4th quarter to play behind the backup offensive line.
Sanchez's injury raised questions about why coach Rex Ryan would put him in the game, especially with backups.
After Smith's poor performance in most of the game, Sanchez was speculated to be the obvious choice for the starting quarterback. Now, it's unclear to what extent he is injured and whether he will be able to play.
