Wales manager Craig Bellamy has stressed that squad depth has been at the heart of his planning since he became boss.
The build-up to Tuesday’s match has been dominated by withdrawals.
Joe Rodon, who completed Leeds’ goalless draw with Newcastle on Saturday, has stayed behind in England after entering concussion protocols.
His absence adds to a lengthening list that already included Ethan Ampadu and Connor Roberts, both omitted from the original squad through injury.
Captain Aaron Ramsey is also unavailable as he continues building up match fitness at Pumas UNAM after hamstring surgery kept him sidelined for five months.
The problems deepened over the weekend, with Wrexham pair Danny Ward and Nathan Broadhead as well as Coventry’s Jay Dasilva all struck down by fresh setbacks.
As a result, Everton goalkeeper Tom King, QPR defender Rhys Norrington-Davies and Cardiff’s Joel Colwill were drafted in.
Yet Bellamy has been unwavering in his message: injuries are part of international football, and Wales are equipped to withstand them.
“It (injuries) has happened since I’ve been manager and, honestly, it was in the Nations League (last autumn),” he explained ahead of the clash in Astana.
“I was using a lot of players then. Now, why was I using a lot of players? Because it’s going to take a lot of players (to qualify).
“Now, we’re ready for these type of scenarios. If we don’t prepare for them, and when you do have this scenario, for instance, then you can get hurt.”

Bellamy highlighted the range of attacking options still available, including Brennan Johnson, Daniel James, David Brooks, Harry Wilson, Kieffer Moore, Liam Cullen, Lewis Koumas, Mark Harris and Sorba Thomas.
Against a Kazakhstan side ranked 114th in the world – 83 places below Wales – that forward firepower could prove decisive.
“Why do the top nations always consistently qualify? Now, of course, they have quality, and they have the squad,” Bellamy said.
“They have three or four teams, and you don’t really talk about all their injuries as much unless it’s one star player…they have experience and (can swap) quality for quality.
“Now, for us, it was about exposing a squad, you know several changes in every Nations League game.
“My part is to prepare (for) this type of scenario and we’re ready. We’re in a good place.
“I never talk about injuries because the simple fact is that it’s reality of the game we’re in. It won’t have an effect on us, we’ll be strong.”

Wales have reason for optimism, having beaten Kazakhstan 3-1 in Cardiff back in March.
They sit second in Group J, a single point adrift of North Macedonia, and victory in Astana would strengthen their push for a top-two finish.
The trip comes with added challenges, including a six-hour time difference and an artificial pitch at the Astana Arena – a surface Bellamy admitted before departure he was “not a fan” of.
But once again, he downplayed any sense of disruption.
“The FAW (Football Association of Wales) have done well, really made it comfortable for us,” Bellamy noted.
“Time difference, we adjust. We’ve been working for this for a number of months, we knew this game was coming and you just have to adapt.”
