Matt Renshaw says Steve Smith "wasn't too thrilled" when the Australia opener retired with an upset stomach on day one of the first Test against India but his captain understood that "when you need to go to the toilet, you've got to go to the toilet."
The situation appeared healthy for the tourists late in the morning session with Renshaw and David Warner at the crease as India failed to make a breakthrough on a Pune pitch which turned sharply.
But both openers were in the pavilion before lunch after an unwell Renshaw followed Warner off the field when the vice-captain was dismissed by Umesh Yadav (4-32).
Renshaw later returned to made an assured 68 and Mitchell Starc smashed 57 not out off just 58 balls in an unbroken last-wicket stand of 51 to leave Australia 256-9 at stumps after they looked set to be skittled out cheaply.
Former Australia captain Allan Border said on Fox Sports that if he was skipper he would not be happy unless Renshaw was "laying on the table in there half dead" following his early departure, but the 20-year-old said Smith sympathised with his predicament.
"It came pretty suddenly," Renshaw said after the opening day of the four-match series. "Maybe five or 10 minutes before Davey got out I asked [umpire] Richard [Kettleborough] how long there was until lunch and he gave me the answer of 'half an hour' and I was struggling a bit then.
"It was tough, I wasn't too sure on the ruling. I didn't know you could retire ill so I just had to get out there and made sure I batted until lunch.
"It wasn't an ideal situation, I just had to make do. Coming back it was a bit strange for me waiting to bat, because as an opener you just go out there and bat, so that was probably the most challenging bit - waiting to bat."
Asked what Smith thought of the situation, Renshaw replied: "He wasn't too thrilled about it but he understands that when you need to go to the toilet, you've got to go to the toilet. It wasn't an ideal scenario but it's life, pretty much.
"Obviously we just lost a wicket so there would be two new batsmen out there but it's a hard scenario to be in and he understood. We've had a chat now and we're all good."
