MELBOURNE: Glenn Maxwell broke his leg in a freak accident and underwent surgery Sunday, selectors said, with the all-rounder sidelined for an extended period, including Australia`s upcoming One-day International series with England.

Maxwell reportedly slipped and fell during a friend`s 50th birthday party on Saturday evening and fractured his lef t fibula.

`Glenn is in good spirits,` said chief Australian selector George Bailey.

`It was an unfortunate accident and we feel for Glenn in the circumstances given he was in great touch in his last few games.

`Glenn is a critical part of our white-ball structure and we will continue to support him through his recovery and rehabilitation.

Local reports said Maxwell and a friend were running in a back yard on Saturday evening when both fell over, with Maxwell`s leg trapped under the other person.

He will miss the three one-dayers with England starting Thursday and could sit out the entire Australian summer.
