Bucks' Damian Lillard, Giannis Antetokoumpo out for Game 4

Milwaukee Bucks stars Damian Lillard and Giannis Antetokounmpo officially have been ruled out for Game 4 of the Eastern Conference first-round series against the Indiana Pacers on Sunday in Indianapolis.

Lillard aggravated an Achilles tendon injury during the late stages of the fourth quarter in Friday's 121-118 overtime loss to the Pacers. Indiana holds a 2-1 lead in the best-of-seven series.

An eight-time All-Star, Lillard was seen in a walking boot on his right foot on Saturday.

Lillard, 33, is averaging 32.3 points, 5.3 assists, 3.7 rebounds and 1.3 steals in three games during this series.

A two-time NBA MVP, Antetokounmpo hasn't played since straining his left calf in a game on April 9.

The series returns to Milwaukee for Game 5 on Tuesday.
