Mamelodi Sundowns' on-loan midfielder to Sekhukhune has allegedly breached Babina Noko's code of conduct.
SABC Sport reports that the 27-year-old arrived in camp "in a poor condition," something that did not please coach Eric Tinkler.
Mbule has been frozen out of Sekhukhune's last two Premier Soccer League games against Orlando Pirates and Magesi FC.
As a consequence, the midfielder is likely not to feature in Babina Noko's last two league games against Kaizer Chiefs and Golden Arrows.
Sekhukhune were believed to be ready to have Mbule beyond the current season, but he will now be sent to his parent clu,b Sundowns.
