Mohomi has been linked with a loan move to Matsatsantsa, but Mosimane wants the midfielder to stay put despite his struggles for game-time at the Absa Premiership champions.
'Jingles' says injuries have slowed down Mohomi, who initially linked up with Sundowns from Free State Stars in July 2016.
"Not yet ... not yet," Mosimane responded when asked if Mohomi will be joining SuperSport.
"He is still with us. We want him here. I think he's got a chance.
"It is not easy for me to say that (if he is joining SuperSport). He is a good player for us.
"He was supposed to play against Maritzburg (but) he got injured on the knee. He was supposed to play because Hlompho Kekana is getting slow towards the end of the match, but he is forever injured."
Mosimane added: "Lucky is injured. Aubrey Ngoma is injured. Those guys need to visit a sangoma and it is not easy because you guys ask why they are not playing.
"Lucky last week got a calf (injury), this week he got a knee (problem).
"He wants to go maybe to SuperSport. I will ask him if he is not going to get injured there."
