Richardson says it has been amazing first-class cricket for him and getting chance to play for Australia with spectators behind him.
He said he doesn't get much time to talk to coach Mickey Arthur.
South Australian quick Kane Richardson has been called up as cover for Sunday's ODI against Sri Lanka at the Adelaide Oval, after Starc picked up the injury during Australia's 107-run series opening win in Melbourne on Friday.
The left-armer took 1 for 25 off six overs, but his status for the remainder of the five-match ODI series remains uncertain.
The Australians are already without several fast bowlers due to injury, including Ben Hilfenhaus and Pat Cummins, although James Pattinson and Josh Hazlewood have returned from being sidelined.
