On December 13, 2014, Conley scored a career-high 36 points to help the Grizzlies defeat the Philadelphia 76ers, 120–115, in overtime. The Grizzlies finished the season as the fifth seed in the Western Conference, making the playoffs once again. They then faced the Portland Trail Blazers in the first round and defeated them in five games. Near the end of Game Three of the series, Conley suffered a facial fracture, which forced him to miss the rest of the first round. He also missed Game One of the Semifinals against the Golden State Warriors. But Conley returned in Game Two of the series; and, while donning a protective mask, he scored 21 points to lead Memphis to a victory. However, Memphis eventually lost to the Warriors in six games.
