[Kansas City.com] Running back Jamaal Charles didn’t play much in the second half of Sunday’s loss in Buffalo because of soreness in his knee, Chiefs coach Romeo Crennel said.

Crennel said Charles was likely to be available in this Sunday’s game against the Saints in New Orleans.

But the situation bears watching. Crennel said the soreness was in Charles’ left knee. Charles tore his ACL in the same knee last season.

Soreness in the knee is normal after such an injury and the resulting surgery.
