Champs keep their crowns

The last time CBS telecast a world title fight in prime time, Muhammad Ali was in the ring - 38 years ago.

Keith Thurman and Shawn Porter did their best to ensure the wait won't be anywhere near so long for the next one, as Thurman defended his WBA welterweight crown with a 12-round unanimous decision in an action-packed slugfest on Saturday night at Barclays Center in Brooklyn.
