Black Caps coach Gary Stead confirmed Rutherford would join the squad on Thursday, as cover for Bruce.
Bruce told Radio Sport Breakfast that his injury needed some rest but wasn't overly serious.
"It was full contact tonight, wasn't it," Bruce laughed.
"I'll ice the knee and rest up the next couple of days – I think it should be right, fingers crossed anyway.
Taylor, meanwhile, has been ruled fit and ready to go, after being left out of today's match as a precautionary measure.
With their resources already stretched to breaking point, Bruce suspects there may be not too many training requirements before the third Twenty20.
"The boys will rest and recover tomorrow, and I'm not too sure if we'll have a training the day before the game or not – probably with the amount of injuries we might just rest up again."
The Black Caps lead the series 2-0, with the final game of the series set to be their last international for nearly two months - giving their walking wounded time to recover before England visit New Zealand shores in November.
