Connacht's injury crisis shows no sign of abating after it was confirmed today that Quinn Roux is expected to be out of action for up to three months with an ankle injury.

Roux was just one of five players who went off injured during his side's 20-16 defeat to Cardiff Blues on Friday evening.

The back row suffered a ruptured ankle syndesmosis and is awaiting a surgical review but looks set to be ruled out until the start of March.

Darragh Leader is also set for prolonged spell on the sidelines after scans revealed that he had fractured the second metacarpal in his hand. 

That injury is likely to keep Leader out of action for two months.

Eoin McKeon was also among the casualties of Friday's game and the province have confirmed that he suffered a elbow medial ligament tear.

McKeon's injury does not require surgery but is still likely to keep him out of action for a month.

Elsewhere Craig Ronaldson and Kieran Marmion both suffered concussions against Cardiff and will undergo the normal return-to-play protocols.

There was a small ray of light for head coach Pat Lam after Ian Porter's ankle injury proved to be less serious than initially feared. 

Porter suffered an ankle ligament sprain but the injury has settled well in past 24 hours and it is hoped that the scrum half will be available for his side's European Challenge Cup game with Newcastle this week.

Meanwhile Bundee Aki (ankle), John Muldoon (calf) and Ronan Loughney (back) all sat out training today and there is a question mark over their availability for the clash with Newcastle.
