Sydney: Uncapped left-arm spinner Jon Holland will join Australia's squad for Friday's triangular series match against Sri Lanka as cover for Xavier Doherty who suffered back spasms during practice on Thursday.

"While Xavier Doherty's injury is not deemed as being serious it is important we have capable cover in Sydney for tomorrow's match," said coach Mickey Arthur in a Cricket Australia statement.

Doherty's availability will depend on a pre-match assessment, the statement added.
