Imagine being an NFL quarterback whose entire livelihood hinges on arm strength and accuracy.

Now imagine being an NFL quarterback who lost to a punter in an arm-wrestling competition. Sounds impossible, right? Not so fast.

Based on an Instagram post by Charlie Whitehurst, the Tennessee Titans backup quarterback lost more than his pride after failing to beat the team's punter in an arm-grappling match.

James Dator of SB Nation spotted the post, which showed a No. 12 jersey with Whitehurst's name on the back. The backup captioned the photo, "Arm-wrestled the punter for #6 and lost #itwasagoodrun6 #13years."

And thus ended the No. 6 era in Whitehurst's life, a period that spanned from his college days at Clemson through his time with the Seattle Seahawks and San Diego Chargers.

Who was this punter? Brett Kern, the Titans' special teams man who had claimed the number long before Whitehurst signed with the team in March.

Christmas Ape of UpRoxx conjectures as to why these two men turned to strength competitions instead of going about the usual "throw me a figure, I'll sell you the number" routine that typically occurs in these situations.

Usually what happens when a new player joins a team and wants the jersey number of an existing player, a cash transaction occurs, usually to the amount of tens of thousands of dollars. But seeing as how this is a backup quarterback we’re talking about, perhaps he can’t be as loose with his money as those other players can.

Nope, Whitehurst probably can't afford to shell out $20,000 for a number. Spotrac.com reports he is signed to a two-year, $4.5 million contract with Tennessee. Nothing to balk at, but he's not exactly make-it-rain rich.

Thus, an arm wrestling match took place—a match Whitehurst lost and will never fully live down.

Chin up, sir. You'll show them all when Jake Locker and Zach Mettenberger go down with hip dysplasia this year and you lead the team to a 7-9 record and flash occasional signs of life. Or you'll have to sit on the bench and do your thing.

Either way, you're still an NFL player making millions. So there's that.
