Russell Westbrook has signed a 10-year extension with Nike's Jordan Brand. The deal will be the richest for any Jordan athlete to date.

Westbrook first joined Jordan Brand in 2013 on a five-year deal.

The increased pay rate will retroactively apply to his 2016-17 MVP season, according to sources.

The deal will include both on- and off-court signature sneakers, new territory for Westbrook. 

The deal also includes a rare "ambassador clause," providing Westbrook with appearance opportunities and additional Jordan Brand legacy potential after he retires from the NBA.
