Defender Broomes is nursing a toe injury sustained in Saturday's home win over Southampton and midfielder McLaren is suffering from illness and was withdrawn in the closing stages at the weekend.
However, striker Bas Savage is suffering from a chest infection and could miss out, while influential defender Ian Goodison will play on despite an ankle problem.
Parry said: "Ian is not going to be 100% now until the end of the season when we're able to rest it and do some further investigation to see if we can do anything in the close season to alleviate the long term problem.
"It's just going to be a matter of managing it."
