The NBA title race has been blown wide open after Brooklyn Nets' star point guard Kyrie Irving severely sprained his ankle during a game four loss to the Milwaukee Bucks this morning.

Irving joins fellow superstar James Harden on the Nets' injury list, and now a second-round playoff series that once looked like a Brooklyn runaway suddenly is up for grabs.

Milwaukee star Giannis Antetokounmpo scored 34 points and the Bucks rolled to a 107-96 game four victory to tie the series.

The Bucks erased a 2-0 deficit by winning two straight in Milwaukee. Game five is Wednesday in Brooklyn.
