NEW YORK (WFAN) - It’s been widely documented that hefty Jets head coach Rex Ryan lost a considerable amount of weight this offseason.

While it’s good to see that Ryan has apparently taken to a healthier lifestyle, it appears that one of his key players has gone in the opposite direction in that regard.

While most professional athletes — especially football players — spend the offseason hitting the weights and improving their agility, Jets running back/kick returner Joe McKnight allegedly spent his time off following the end of the NFL season in fast-food heaven.

Yes, you heard that correctly.

The 24-year-old — who was an All-Pro selection this past season — gained 16 pounds this offseason by stuffing himself with loads of McDonald’s, CBSSports.com reported.

And the Southern California alum wasn’t particularly shy about admitting his junk-food vice.

“I was eating healthy, but the majority of time I was eating bad,” McKnight told reporters. “I wasn’t eating all the right stuff … Like Tim Tebow.”

McKnight, who was drafted by the Jets in the fourth round of the 2010 NFL Draft, averaged just 3.1 yards per carry and didn’t score a touchdown in 2011.

Who knows, maybe some Big Macs and chicken nuggets will do the running back some good? Share your thoughts on this awfully strange story below…
