Portland later led 115-108 after two free throws by Sharpe with 11.1 seconds remaining before Memphis narrowed the gap prior to the buzzer.

In regulation, the Trail Blazers trailed 100-90 before Brogdon scored eight points during a 12-2 burst that forced overtime. Brogdon's two free throws with 45.6 seconds left pulled Portland within 102-100, and Sharpe made two from the line with 8.3 seconds left to tie it.

The Trail Blazers shot 40.6 percent from the field, including just 9 of 32 (28.1 percent) from 3-point range.

Memphis connected on 49 percent of its shots but was just 10 of 35 (28.6 percent) from behind the arc.

Bane converted a layup and Roddy scored on a fastbreak dunk to give Memphis a 10-point advantage with 3:21 left.

Memphis led 77-76 entering the final stanza.
