John Ryan joins London Irish from Munster on loan
London Irish have signed Munster prop John Ryan on a short-term loan.
The 23-year-old, who can play either tight or loose head, has played for Munster five times in the Pro12 and been on the bench in the Heineken Cup.
Ryan was not involved in Friday's pre-season friendly when the Exiles beat Munster 34-10.
He is likely to go straight into the Exiles squad for Saturday's Premiership opener against Saracens, which will be staged at Twickenham.
