Kyler Murray was in the midst of a magical day leading a road upset against the Seattle Seahawks when an injury popped up.

The Arizona Cardinals quarterback suffered a hamstring injury on a third-down scamper early in the third quarter.

The story said Murray was shown by cameras on the sideline looking frustrated by the injury. The Cards officially ruled Murray as questionable to return but he never did. It's perhaps a bit of good news he was first ruled as questionable. But with Week 17 not meaning much, those counting on Murray may have to find a backup plan.

Oklahoma coach Lincoln Riley told "The Dan Patrick Show" in March that Kyler Murray was "a tremendous leader" a sentiment Larry Fitzgerald concurs.

Fitzgerald was impressed by Murray's immediate confidence with the Cardinals during their three-day minicamp in June.

"I know him running Lincoln Riley's offense (at Oklahoma) is very similar to what Coach Kliff Kingsbury runs, but on the first day he's calling audibles and getting us in plays that are favorable to the offense," Fitzgerald told SI. "So I was really impressed by his ability to take a leadership position first day at offense. I was impressed with how smart he is, how determined he is. His future is extremely bright."

Murray said he probably knows the system better than anyone on the Cardinals right now, but added that's his job. Fitz mentioned Murray makes the audibles quickly, and once the players adjust, the offense will run faster. Murray is already a top-10 QB in our rankings coming in 10th and we obviously think he has a shot to put up QB1 numbers in his first season.
