Scrum-half Aaron Smith revealed he was "physically wrecked" after the Highlanders' thrilling win over the Chiefs.
The Highlanders won their first play-off game for 16 years with the 24-14 victory to advance through to the semi-finals.
Smith played a huge role with two assists, both for tries by Waisake Naholo, and the All Blacks star didn't hide his emotions afterwards.
"I am mentally and physically wrecked," Smith told Stuff.
"That's how I wanted to feel (after the game). I didn't want to feel like I had anything else left. I really just want to go and have a shower and reflect.
The cost of Saturday's triumph will be counted in the next few days with injuries for Dan Pryor, Alex Ainley and Malakai Fekitoa.
Head coach Jamie Joseph believes however that Fekitoa will be ok, while acknowledging the effort from his players.
"Because it's an eye there's obviously some sensitivity around that area but I think [Fekitoa] will be fine," said Joseph.
"They (the players) are lying on the ground now, mate. They are buggered. It's not really a big concern for us. They will recover, have a couple of beers and get on with it."
