The most watched hamstring in the NFL belongs to Buffalo Bills running back LeSean McCoy. He's been sidelined since mid-August with a hamstring injury, but he was able to return to practice on Wednesday.

After practice, though, McCoy gave everyone yet another update on his injury. Contrary to Rex Ryan's information shared Wednesday, McCoy isn't as confident in his health for Week 1.

"I'm not sure I'll be 100 percent, but I'll be ready to compete," McCoy said via Matthew Fairburn of Syracuse.com.

It's been widely speculated that even if McCoy is able to play against the Colts, he won't be fully healthy, with the possibility of being on a "pitch count." McCoy didn't exactly silence those thoughts with his comments, but he'll be on the field at the very least.

The Bills will need all the help they can get against the high-powered Colts' offense as they'll look to keep pace with Andrew Luck and company.
