No one knows for sure if Arizona Cardinals wide receiver Larry Fitzgerald is going to retire at season's end, but Fitzgerald isn't stressing over what will surely be a tough decision:

“I told you guys, it’s a job,” said Fitzgerald, according to Josh Weinfuss of ESPN.com. “I love what I do, but when it’s over, it's over and I’m not going to lose any sleep.”

While Fitzgerald hasn't officially made a decision yet, it does seem like he is leaning toward calling it quits after this year:

“I’ve got a lot of great things ahead of me … everybody’s replaceable,” he said, per Weinfuss. “There’ll be another No. 11 here in a couple months after I leave. He might not be as handsome as I am though.”

Whether or not those “couple of months” after he leaves will be after this season or after 2020 or whenever is the question, but there is no denying Fitzgerald's tone.

Still, it remains to be seen.

Even in his old age, Fitzgerald remains productive, as he has logged 67 catches for 711 yards and three touchdowns this year.

The 36-year-old, who played his collegiate football at the University of Pittsburgh, was originally selected by the Cardinals with the third overall pick of the 2004 NFL Draft.

It didn't take long for Fitzgerald to stamp his name among the league's best wideouts, as he led the NFL in receptions and made the Pro Bowl as soon as his sophomore campaign.

Overall, Fitzgerald has made 11 Pro Bowl appearances while notching First-Team All-Pro honors once throughout his illustrious NFL career.
