Bucks' Lillard returning for must-win; Giannis out

The availability of Milwaukee Bucks stars Damian Lillard and Giannis Antetokounmpo for a must-win Game 6 against the Indiana Pacers will be a game-time decision, coach Doc Rivers said Thursday afternoon.

Lillard, who was doing his pregame warmups, was upgraded from doubtful to questionable earlier Thursday as the Eastern Conference first-round series continues tonight in Indianapolis.

"Giannis is more doubtful than Damian, but both had great workouts today," Rivers said.

Antetokounmpo, a two-time NBA MVP, was listed as doubtful on the NBA injury report as he deals with the calf injury that has kept him out of the series and off the court since April 9.

Lillard has sat out the past two games with a right Achilles injury. The eight-time All-Star averaged 32.3 points in the first three games of the series for the Bucks, who trail 3-2 in the best-of-seven series.

On Tuesday, Rivers described Lillard and Antetokounmpo as "very, very, very close" to playing.

Without Lillard and Antetokounmpo in the lineup for Game 5, Khris Middleton and Bobby Portis scored 29 points apiece in Milwaukee's 115-92 victory over Indiana on Tuesday. The win made the Bucks the first team in NBA history to win a playoff game while missing its top two scorers from the regular season.
