"I'm here, I'm 100 percent, you could say 110 percent," Charles said, via The Kansas City Star. "I'm on the field, I'm playing."
Returning from the second torn ACL of his career, Charles was originally expected to debut at Oakland in Week 6. He was pushed into a third-string capacity last week when Charcandrick West came down with an ankle injury.
Coach Andy Reid confirmed that Charles will "probably do a little bit more" this week "as long as there are no setbacks."
"I feel like I'm fast, my speed never left," Charles added. "My gift is speed. And I still have it. I just thank God for allowing me to keep my speed."
