Ja Morant revealed he played the final four games of the restart with a fractured right thumb.
Morant scored a season-best 35 points in a 126-122 loss to the Portland Trail Blazers in the play-in game.
"For the past four games, since the [Toronto] Raptors game, I was out there playing with a fractured thumb," Morant said Saturday.
Memphis had a 3½-game lead over Portland for the No. 8 spot when the season went on hiatus on March 11.
"I can say I'm disappointed, definitely, with losing," Morant said. "Nobody likes to lose. But I mean, the positive side, we know we were right there. Just were two games away [from the playoffs]. So, we know we just go back to work and just get ready for next season."
