London Irish have completed the signing of former South African international hooker Danie Coetzee.
Coetzee has won 14 caps for the South Africans
The 28-year-old, who has impressed for South African side Blue Bulls during this season's Super 12 tournament, will link up with the Exiles in November.
Irish have also signed New Zealand prop Michael Collins, 31, who will join the club in the summer from Waikato Chiefs.
"There were times last season when there was insufficient depth in key positions," the club said.
