Bell has recovered from an ankle operation and returned to training last week.
Speaking about Bell's inclusion in the squad, Chris Coleman told the CT: "David trained with us last week and I am going to put him in the squad.
"Obviously, he can't start and ideally we want him to go out on loan to try and get some games but if we keep losing bodies we won't be able to do that.
"Fitness wise that's what he needs before he comes to us but at the moment I am going to put him in the squad for a bit of experience."
