CLEVELAND (REUTERS) - Cleveland Cavaliers guard Matthew Dellavedova was hospitalised after experiencing "severe cramping" following his team's victory over the Golden States Warriors in Game Three of the National Basketball Association Finals on Tuesday.

The feisty Australian, who has done a brilliant job in place of injured All-Star Kyrie Irving, required an IV that prevented him from meeting with the media after his 20-point performance helped Cleveland take a 2-1 lead in the best-of-seven series.

Dellavedova will continue receiving treatment during the night at a Cleveland hospital and his status will be updated on Wednesday afternoon, the Cavaliers said in a statement.
