He might have to squeeze in a beer with his team-mates as well.
Whatever happens, you can guarantee the veteran hooker will have a broad smile on his face.
He has been bashing into blokes for Otago for 15 years and will become the 23rd player to bring up 100 games for the province when he emerges from the bench for the Ranfurly Shield defence against North Harbour today.
It is a big day for the 35-year-old with the glorious beard.
"Yeah. It’s an exciting week, especially having the Ranfurly Shield," he said.
"There’s a lot of buzz around that as well, so it’s going to be a good weekend.
"I’m looking forward to the match."
His mother and father will be at the game and his wife, Aleisha, and daughters Tilly, 7 and Ruby, 6 will be there too.
"They’ll be here cheering me on and I’ll be very proud.
"I still can’t believe it, to be honest. The first one was such a buzz and so it’s still a buzz now."
Let’s wind the clock back.
Coltman moved to Dunedin from Taranaki to study physical education, but rugby quickly became the priority.
He made his debut against Counties-Manukau in July 2010.
Counties won comfortably, but the following week Coltman played in a game every Otago fan remembers.
The team headed south to challenge a talented Southland side for the Ranfurly Shield.
The match was controversial.
Stags prop and captain Jamie Mackintosh barged "over" to score a try and put the home team ahead with 12 minutes remaining.
And by over, well, we use that term very loosely, as the photographic evidence suggests the ball was well short of the chalk when he grounded it. Regardless, the Stags won 16-12.
Former Otago Daily Times rugby writer Stephen Hepburn wrote "even Stephen King could not pen something this ghastly, this painful and this darn sad".
Much happier Ranfurly Shield memories awaited Coltman, and Hepburn, for that matter.
The shock 26-19 win against Waikato in 2013 ended a 57-year drought and Coltman was in the side that won it again in 2020.
Last Saturday’s 38-36 Ranfurly Shield win against Canterbury was something special as well, perhaps even his favourite game in Otago colours.
"It’s definitely right up there with the way the boys did it. We had a man in the bin, a few points down, 20 minutes to go, that was massive.
"That’s only the third time I’ve ever beaten Canterbury, so it’s definitely right up there.
"But also that Shield challenge in 2013. To win it for the first time in such a long time, to see what it meant to the province was absolutely massive, so probably those two are right up there."
Coltman played a key role in the win against Canterbury.
He scored from a lineout drive and Cameron Millar’s conversion put them ahead with 13 minutes remaining.
Otago had trailed 36-21, so it was a remarkable fight back.
Coltman has no immediate plans to give the game away despite "a few of the boys" kindly pointing out to him they were toddlers when he started playing for Otago.
"That’s pretty funny, but yeah, it’s awesome being able to be in this environment for so long. It’s been an absolute pleasure.
"I’ll most likely head back to the States for next season and then we’ll see what happens from there."
