Per NFL Media Insider Ian Rapoport, McCoy's tweet on Friday morning was indeed a declaration of his playing status for Sunday's game against the 5-0 Bengals in Orchard Park.
Teammate Mario Williams was live on NFL HQ on Friday morning when McCoy's tweet went live. The pass rusher hoped it was a sign of good things to come.
"I'm glad. I'm glad," Williams said. "I pick at him just about every day because sometimes I ask him if he's even on the team anymore. I'm glad that we'll have an opportunity to have him back out on the field. Hopefully he's out there and if he's out there, like I said, that's another plus for us to have an opportunity to win the game."
With Tyrod Taylor out, any versatility to the ground game will be appreciated for EJ Manuel and offensive coordinator Greg Roman. Though McCoy is only averaging 48.7 yards per game and seven catches, he's clearly been hampered by injury. This could be the first week we're actually seeing him close to 100 percent.
