Cape Town - Trevor Nyakane's ill-discipline has become a problem which the prop must sort out if he wants to return to the Springbok squad.
Nyakane, 24, was on Sunday axed from the Bok squad for disciplinary reasons, with official word from the Bok camp saying he "repeatedly breached team protocol".
The Cheetahs prop missed a flight to the Bok training camp last week and also missed a video session without permission.
He is also unfit, and sources close to the team told the Beeld website Nyakane's "constant eating" is a big concern for the Bok coaching staff.
Nyakane was among 30 players chosen for home and away Tests against the Pumas at the start of the Rugby championship, but did not make the match-day 23 in the 73-13 rout of Argentina at FNB Stadium over the weekend.
The 118kg front-ranker rose to prominence as a second-half impact player for his franchise and won his first Springbok cap against Italy last June as a replacement.
He also came off the bench against Scotland and Samoa in other four-nation tournament games and is considered a long-term challenger to tighthead incumbent Jannie du Plessis.
Coach Heyneke Meyer replaced Nyakane with uncapped Lourens Adriaanse in his 26-man touring squad while Piet van Zyl took the place of unavailable scrumhalf Fourie du Preez.
The Boks tackle Argentina in Mendoza on Saturday (kick-off 21:10 SA time).
