Injury roundup: Andre Johnson (concussion) ruled out

Andre Johnson's Sunday finished prematurely.

The Texans' Pro Bowl wideout was ruled out for the remainder of Sunday's game against the Jaguars due to a concussion, the team announced. Johnson left for Houston's locker room to be evaluated for a concussion after taking a crushing helmet-to-helmet hit from Jaguars rookie Telvin Smith. 

Johnson accounted for a team-leading 17 yards off four catches against Jacksonville before exiting the game.

In his absence, Texans quarterback Ryan Fitzpatrick leaned heavily on productive young wideout DeAndre Hopkins through the air.

Here are some other injuries we're tracking this Sunday:

1. Cardinals cornerback Antonio Cromartie was carted off the field with a lower leg injury and never returned. NFL Media Insider Ian Rapoport reported that Cromartie will have an MRI on his lower leg on Monday, but the injury doesn't appear to be serious.
