Muhammad Ali Sends Dirk Nowitzki Boxing Glove That Says ‘You are the Greatest’ After Mavericks’ Championship Win

Muhammad Ali told the world during his boxing career that he was the greatest. But now he's apparently handed that honor over to a new champion — Dirk Nowitzki of the Dallas Mavericks.

Nowitzki said that Ali sent him a boxing glove with the inscription, "You are the Greatest," upon the Mavericks' NBA Finals win, according to the German weekly magazine Spiegel.

Nowitzki, who was named the MVP of the Finals, said that he was happy to receive the gift and that he returned the favor by sending Ali a golden basketball with a similar inscription.

The Dallas Mavericks defeated the Miami Heat in six games this past season to captured their first NBA championship in franchise history.
