Singer Kaneswaran, 34, has been impressing viewers with his skating performances alongside Klabera Komini so far, but sadly he will not put in another routine this week.
He has been ill this week and on the advice of doctors will be resting this weekend rather than taking to the ice again tonight.
Kaneswaran said: "I'm gutted that I won't be performing this weekend but I picked up a bug earlier in the week which I haven’t been able to shake so I need to rest and get myself better.
"Good luck to all the contestants this weekend - I'm looking forward to watching everyone's performances!"
A Dancing On Ice spokesperson confirmed: "Due to illness Siva will not skate in this weekend's show. We look forward to welcoming him back next weekend."

It will be the first time this series that a contestant has not been able to skate due to illness or injury.
The previous two series of Dancing On Ice saw a number of celebrities and their pro skating partners ruled out of various weeks of the competition after being injured in training or getting ill.
In the 2021 competition, both reserve celebrities had to be called in to bolster cast numbers and the show still took a week's break mid-series and ended early after five contestants were forced to pull out.
Talking before the series about his reasons for signing up, Kaneswaran paid tribute to his late bandmate Tom Parker who died of a brain tumour last year.
He said: "I’ve decided this year to do a lot of things that I’d never do and face my fears. Obviously, this year has been eye-opening for me with Tom and witnessing his courage, which was infectious to say the least. It reminded me that life was worth living and to take it all and to enjoy it.
"In comparison, it’s just not as scary anymore, all my fears have shrunk."
Dancing On Ice continues tonight at 6.25pm on ITV1.
