'Shabba' was tackled in the second half of the first semi-final, which Chiefs won 3-0, and was replaced by George Lebese.
Chiefs coach Stuart Baxter confirms that there is a possibility that the Bafana Bafana midfielder could be out for a long time due to the injury.
"Shabba got a quite nasty one so we have to wait a couple of days before we can be sure how long he is going to be away. But certainly he is not going to be training tomorrow anyway," he says.
Chiefs will start the season against Mamelodi Sundowns in the MTN8 quarter-final early next month.
Overall Baxter was pleased with how his side performed during the inaugural Gauteng Challenge, which Amakhosi won after beating Bidvest Wits 8-7 on penalties in the final.
"The total performance of the players today, I'm very pleased. I thought we played better in the first match against Swallows, and in the afternoon we made quite lot of changes and the boys didn't find the rhythm in the first half but they kept going and we happy to have won in the end," Baxter says.
And with the players the team has assembled this season, the former Bafana Bafana coach is convinced that Chiefs will make the grade this coming season, but refused to be drawn on what his team will win.
"When I started here at Chiefs I said the only promise we can make is that we will go full house and everybody will give every drop of bullet they got for Chiefs. And I will make my promise again, we will keep on trying to improve, we will keep on trying to be a better team and to try to keep a smile on our supporters' faces," Baxter says.
