The Team of Choice took the decision to tie down Rusike until June 2019 following media reports that Orlando Pirates wanted to sign the striker.
Chairman Farook Kadodia told Goal on Monday that there was no truth in the reports, saying they have not been in talks with the Buccaneers.
Kaizer Chiefs were also believed to be keen on the Zimbabwean frontman last season, but the KwaZulu Natal outfit decided against selling their top striker.
Rusike is excited that he has been afforded another opportunity to keep improving his game at the Team of Choice.
"I was happy to join the club last season and help to survive relegation. Now that the club has exercised the option, I have to stay focused. I have a job here. It’s an opportunity for me to keep improving on my game," Rusike told the club's website.
Meanwhile, marketing and communications manager Brian Zuma echoed his chairman's sentiments that Rusike was not for sale.
He said proper channels will have to be followed should any of the PSL teams show interest in Rusike.
"Evans is our property and we're still expecting a lot from him. He is not for sale until the time is right, and if and when that happens, proper channels will have to be followed.”
