Kevin Love was cleared to fly back to Cleveland, but his playing status remains up in the air.
The Cavaliers forward, who suffered a concussion on Sunday in Game 2 of the NBA Finals, traveled with his teammates on Monday as they regrouped after a second straight blowout loss to the Golden State Warriors. A Cavs spokesman said in an email that Love was on the team flight from San Francisco to Cleveland.
It's not yet known whether Love will play again in the series. He is following the NBA's concussion protocol, which requires him to be symptom-free and pass certain requirements before he can be cleared by a physician to return to the court.
Game 3 is Wednesday night.
The loss of Love is another blow to the Cavs, who have been outclassed by the defending champion Warriors.
Love was inadvertently struck in the back of his head in the second quarter by Golden State forward Harrison Barnes while fighting for a rebound. Love was taken to the bench and checked by a Cavs trainer before returning to the game. However, Love appeared dazed in the third quarter and removed himself. He did not return, finishing with five points.
After the game, the Cavs released a statement that said Love "did not exhibit any signs or symptoms during the first half, or at halftime, that would have caused him to be placed in the concussion protocol prior to the third quarter."
If Love can't play, Lue has several options. He could go with a bigger starting lineup and play center Timofey Mozgov, moving Tristan Thompson to power forward alongside LeBron James. He also could stay with a smaller starting group and play Channing Frye, who has played sparingly so far in the series, in Love's spot.
Curry won't play in Olympics
Golden State guard Stephen Curry has withdrawn from consideration from the Olympics.
Curry said Monday in a statement that he has decided to pull out because of "several factors, including recent ankle and knee injuries."
He didn't say what the other factors might be. Several athletes have expressed concerns about the water situation in Rio and the Zika virus.
Team USA already is without NBA All-Stars Chris Paul and Anthony Davis, who also have withdrawn.
