According to the Football411 website, Scott clashed with Willard Katsande in the 20th minute of the Urban Warriors' 3-1 win over Kaizer Chiefs on Wednesday, and was substituted shortly after.
A short statement on the Ajax website read: "Granwald played an integral part in Ajax CT this season making 25 starts scoring two goals.
"Scott was selected to captain the side at the start of the season but relinquished his armband to Nazeer Allie to concentrate on his duties in the middle of the park."
The club's public relations officer Shooz Mekuto added: "Losing the services of Granwald Scott is a blow but as we saw last night his replacement Toriq Losper did very well."
