The setback comes as a bitter blow for Muldoon having not been long back from a similar injury – a fractured bone in the same arm – sustained in Ireland’s clash with New Zealand in June.
That injury marred Muldoon’s third appearance in full Irish colours and saw him out of competitive action until October.
And after hearing the news of Muldoon’s diagnosis Connacht coach Eric Ellwood was quick to offer some words of encouragement.
"It's a big blow for John,” said Ellwood – whose side went down 15-9 to Quins thanks to five penalties from Kiwi fly-half Nick Evans.
“He is not long back from a similar injury. But he is a great pro and he will work extremely hard to get back as soon as possible and the picture should be a lot more clear after the scan.”
