EUGENE, Oregon (Ticker) -- Luke Jackson gave himself another chance to play at MacArthur Court.

Jackson scored 31 of his 40 points after halftime as the Ducks rallied from an 18-point deficit for a 77-72 overtime victory over Colorado in the first round of the National Invitation Tournament.

The Buffaloes had their largest lead, 48-30, after David Harrison converted a three-point play just over two minutes into the second half. The Ducks' 24-game home winning streak against non-conference foes was in serious jeopardy until Jackson bounced back from a poor first half.

Facing his last home game, Jackson scored 19 points in the final 18 minutes of the second half while Colorado floundered, managing just 16 points through the end of regulation.

Jackson buried a 3-pointer with 20 seconds left, then scored 14 of Oregon's 16 points in overtime, including 11 from the free-throw line.

The Ducks advanced to a second-round matchup with the winner of Friday's game between George Mason and Austin Peay.

Harrison had 26 points on 10-of-15 shooting and 12 rebounds but got little help as Colorado (18-11) made just 5-of-21 shots in the second half.
