The Arizona Cardinals entered tonight's contest against the Denver Broncos with rookie quarterback Josh Rosen under center. Rosen started the season as the backup to Sam Bradford, but after Bradford's ineffectiveness early in the season was thrust into the stating role.
It hasn't been all sunshine and rainbows for the rookie quarterback. Arizona fields the league's worst offense in terms of yards per game and second-worst in points per game.
Tonight's game against Denver got off to a rocky start as Rosen's first pass of the game was tipped, intercepted and then returned for a touchdown.
Since then, another Rosen pass was intercepted and returned for a touchdown as well. He's also been under attack from the Denver pass rush.
He was sacked by Broncos linebacker Shaq Barrett. During the sack, Rosen's head hit the ground and he then went to the medical tent.
Rosen had a history of concussions at UCLA.
Let's hope this is nothing serious.
UPDATE: Rosen returned to the game.
