Agar out of BBL08 with dislocated finger

Ashton Agar has suffered another setback in his tumultuous summer, with the spinner ruled out for the remainder of the KFC Big Bash season after dislocating his finger.

The Perth Scorchers confirmed Friday that Agar is set to undergo surgery on his right index finger in the coming days following a training injury.

It's unknown how long Agar will be on the sidelines for, nor whether he'll be available for the resumption of the JLT Sheffield Shield season.

"Ash Agar unfortunately suffered a fracture dislocation to his right index finger whilst fielding at training yesterday," Scorchers sports medicine manager Nick Jones said.

"Ash sustained an intra-articular fracture that will require surgical repair. We expect that Ash will undergo surgery in the coming days, and as a result will be unavailable for the remainder of the BBL."

Will Bosisto has replaced Agar in the Scorchers' squad to face the Hobart Hurricanes at Optus Stadium on Friday night.

The injury puts Agar in doubt for Australia's upcoming limited-overs tour of India, which begins February 24. A five-match ODI series away to Pakistan is set to follow.

It's the second time in 16 months Agar has dislocated a finger on his right hand, having damaged his little finger during Australia's limited-overs tour of India in September 2017.

Having begun the 2018-19 season in Australian squads for all three formats, Agar's immediate international prospects appear clouded.

While he was included in Australia's Test and T20 squads to play Pakistan in the UAE and then subsequent limited-overs squads for series against South Africa and India, Agar was largely overlooked and bowled just 30 overs in total between September and December.

He was then dropped for the Gillette ODIs against India, while he was also granted a request to sit out Western Australia's final Sheffield Shield game before the BBL break.

"I was just really struggling. I wasn't very happy and cricket just seemed to make it worse and worse," Agar told Seven West Media.

"I took that week just to regenerate and get my mind right and now I feel a lot better.

"There's been a lot going on. A lot of travelling, a lot of cricket so after all of that, you are only human, I guess.

"I think it was more of a build-up of a really, really busy, solid few months so I think it's more of a one-off thing really.

"People aren't always going to understand and, to be honest, I don't really care if they do or don't because you have to look after yourself."

While he's only taken five wickets in seven BBL games this season, he's been among the competition’s more frugal bowlers with an economy rate sitting a little under seven runs per over.
