Taylor is the most likely starter, having described his absence this morning as a "precautionary measure".
"I swung at the ball a bit too hard, swung and missed, and felt [the hip flexor] twinge a little bit – more of a precautionary measure, nothing major."
His replacement Bruce filled in admirably, making 53 from 46 balls in a record 109-run stand with Colin de Grandhomme, until he also picked up a knock in the dying moments of the clash.
Bruce told Radio Sport Breakfast that his injury needed some rest but wasn't overly serious, though he expected Guptill to be unavailable for the dead rubber.
"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. I think Guppy might be struggling a wee bit."
And 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."
