It was less than two weeks ago that Kansas City Chiefs running back Jamaal Charles went down early in the second half against the Chicago Bears with a torn ACL in his right knee.

Chiefs coach Andy Reid said on Wednesday that both Charles and cornerback Phillip Gaines were under the care of Dr. James Andrews, and that both had successful surgeries.

"Reports were good," he said.

Charles let everyone know via social media that his surgery was a success and that he's now on the road to recovery.

Unfortunately, Charles has actually been through this rehab process before.

It was back in 2011 that he suffered a torn ACL in his left knee, and although it's going to be a tough road to get back before next season, the fact that he's been through this before should help him over the next several months.

Before his injury, Charles had carried the ball 71 times for 364 yards and 4 touchdowns this season.
