Australian greats Greg Chappell and Clarrie Grimmett will be inducted into the International Cricket Council's Hall of Fame on Saturday during a presentation at the Adelaide Oval.
Clarke paid rich tribute to googly bowler Grimmett who made his international debut at the age of 34 and went on to become the first bowler to take 200 Test wickets.
"Legend has it that he invented the flipper and bowled with his cap on so the batsmen could not see where he was aiming his leg-spin," Clarke said.
Grimmett's son, Vic, will receive the ICC Hall of Fame cap on his father's behalf during the presentation.
Clarke was also effusive in his praise for Greg Chappell.
"Greg Chappell's statistics speak for themselves. The fact he was named in the Australian team of the century, is an Australian Cricket Hall of Fame inductee and was honoured by the Queen in 1979 with an MBE for services to cricket are a reflection of a man who has given to cricket as much as he has received," Clarke said.
Prior to play on day two of the Test, seven South Australian volunteers will be honoured for their contribution to cricket when they receive an ICC Centenary Volunteer Medal.
