Robin Peterson Replaces Injured Aaron Phangiso
Phangiso will be on the sidelines for between four and six weeks and will miss the November tour which comprises three Twenty20 Internationals and five One-Day Internationals.
"Aaron sustained a grade two ligament sprain of a joint of the middle finger in his left hand," team manager Dr Mohammed Moosajee confirmed.
"The injury was sustained during a Sunfoil Series match for the bizhub Highveld Lions three weeks ago, and was aggravated during the current tour.
"He complained of discomfort over the last few days, and a subsequent MRI scan on Friday confirmed the severity of the injury."
Peterson, who has played 77 ODIs and 20 Twenty20 Internationals, has taken nine wickets in the early part of South Africa's domestic season, including a haul of five for 25 in a Momentum Cup one-day game for the Cape Cobras against the Warriors.
His last ODI appearance came in November 2013 and he hasn't featured in the T20I team since March 2013.
The first T20I against Australia is on 5th November.
