London Irish sign Munster prop Alan Cotter

London Irish have signed Munster prop Alan Cotter on a short-term deal, replacing team-mate John Ryan.

Cotter, 25, has come in as an injury replacement for Leo Halavatau, who picked up a calf injury on Saturday.

The Limerick-born forward, came through the Munster academy and is on the bench for this weekend's game against Bath.

"John Ryan did a fantastic job for us while he was here and we are sure Alan will make a similar impression," said Exiles director of rugby Brian Smith.
