Jamaal Charles certainly sounds like he's back. Ten days after his season debut, which resulted in two carries and seven yards, Charles hinted that he'll see a heavier workload against the Raiders on Sunday.

OK, he did more than just hint at it.

"I'm ready to let the training wheels off," Charles said, per The Kansas City Star. "I don't want them on. I know how to ride. Take them off and let me ride."

Just in case you weren't already convinced, Charles added that he's "110 percent" and Chiefs coach Andy Reid said Charles will "do a little bit more," which pretty much settles the debate over how much of him you'll see this weekend.

Lock him into your Fantasy lineups, because he's got a favorable matchup. The Raiders might be 4-1, but they're also bad defensively, ranking 29th in defensive DVOA, 32nd in yards allowed per game, and 24th in points allowed per game.

The Chiefs have been productive running the ball too, even without Charles. They're averaging 4.3 yards per attempt, with Spencer Ware doing the heavy lifting.

Still, Charles will be a bit of an unknown in the sense that his 2015 season ended after five games when he tore his ACL (the second ACL tear of his career). At 29 years old, it's possible he could be nearing the end of his productive days as an NFL running back.

He's rushed for 7,227 yards (averaging 5.5 yards per rush) and 42 touchdowns in his incredible career.
