Cardinals CB Antonio Cromartie left Sunday's game with leg injury
The cornerback's injury came in the fourth quarter, when he attempted to tackle Chiefs' receiver Albert Wilson. The team initially indicated that Cromartie had an injury to his left achilles, and that his return to the game was questionable.
Coach Bruce Arians said after the game that Cromartie's achilles was not affected, though the exact nature of the injury is still unclear.
"We were fearful that it was an Achilles, but we don't know quite what it is yet," Arians told reporters.
"They are doing ultrasounds and things on it, but it's not his Achilles...we'll keep out fingers crossed on that one."
Ian Rapoport of the NFL Network reported on Sunday evening that Cromartie did not appear to regard the injury as "serious."

Cromartie, 30, is in his ninth year in the league and his first season with Arizona. He has played in all 13 of the Cardinals' games this year, making 35 tackles and intercepting three passes.
Cromartie is the latest Cardinal to sustain an injury. Quarterback Carson Palmer went out for the year with a torn ACL and running back Andre Ellington is to be placed on season-ending IR with a sports hernia. Receiver Larry Fitzgerald had been hindered by an MCL sprain, while cornerback Tyrann Mathieu has been dealing with a fractured thumb.
The NFC West first-place Cardinals defeated the Chiefs, 17-14, and improved their record to 10-3. They travel to St. Louis next week to play the Rams (6-7, fourth in the NFC West).
