Both players, who have been key parts of Chris Coleman's squad at Euro2016, will miss out on the semi-final against Portugal in Lyon on Wednesday night due to suspensions.
"It's been fine," the Wales skipper said. "The strength is in the squad, not just the team.
"The 23 men who are there. Whoever the gaffer picks will do the job.
"We're disappointed for them, but it gives two others a chance to experience the Euros. They'll fill the slots as good as the boys who went out."
