But while he admits that he will be happy to see conditions in his favour at a sold-out Suncorp Stadium, he is determined to put the needs of the team first against a Reds side boasting 12 Qantas Wallaby internationals within their matchday 23.
"I'm hugely excited. I can't wait for tomorrow to come around. I'm imagining it will be quite a fast-paced game and a ball-in-hand game, one which suits my style," said Gray, who knows that simply doing his job is the best way to press for a Test spot in such a competitive position.
"We've set our stall out and the plan is to play rugby, and to play expansive rugby. That's something I'll look to get involved in.
"My role within the team is my prime concern at the moment. If I can keep improving in that and keep delivering in that, then I'll be happy.
"There's quality across the board in the second rows. Everyone's in the same boat - you've got to take your chances.
"But it's not about being an individual, it's about performing your role within the team. If you prove you can do that, then you put your hand up."
Gray will line up alongside England's Geoff Parling in the third of The Lions' 10 tour fixtures having begun the match against the Baa-Baas next to Paul O'Connell and finished it with Alun Wyn Jones.
The 24-year-old has been impressed with what he's seen from the Leicester lock in training so far and is looking forward to linking up with him for real as The Lions look to make it three wins from three.
"It's been great so far: I've really enjoyed working with Geoff, especially at lineout time and particularly with his attention to detail," added Gray.
"He takes a huge amount of responsibility and a huge amount of pride in the lineout. His lineout work is excellent but he's very strong around the park as well.
"I've learnt a couple of things from him this week. That's been the brilliant part: with different partnerships you get to learn different things."
Richie Gray shone in The Lions' eight-try win over the Baa-Baas on June 1 in Hong Kong
Gray's opening match in Lions colours was his first of any sort in 12 weeks following the hamstring injury that brought his involvement with Scotland and Sale Sharks to a premature end this season but he somehow got through the full 80 minutes despite the heat and humidity in Hong Kong.
It was a major stepping stone for Gray - who admits he was concerned that he might miss out on The Lions altogether - and now he could find that his extended absence towards the back end of the season actually stands him in good stead for the rest of the tour.
"I was worried about missing the tour. I didn't know the extent of my in jury right away. However, I got the scans and they said a period of six to eight weeks, so it gave me a window to get myself right and put my name in the hat. Thankfully, with the help of my physio, I was able to work very hard in getting there.
"It's been incredible so far. I've thoroughly enjoyed it and it just keeps getting better.
"I don't know if fresh was the word in Hong Kong! From a freshness point of view, it's just about trying to get my match fitness back.
"I feel fantastic. I was delighted with how the Barbarians match went - it couldn't have been tougher conditions but I managed to get through it.
"It's 'miles in the tank' as they say. I'll now crack on again this week."
