TORONTO -- Canadian international Phil Mack has signed a short-term contract with the Ospreys, joining fellow Canadians Jeff Hassler and Tyler Ardron at the Welsh rugby club.
Injuries to halfbacks Rhys Webb and Tom Habberfield left Ospreys with only Tito Tebaldi at scrum half.
"We are pleased to have been able to secure Phil's services and he will provide us with some much needed cover in a crucial position over the coming weeks.
"With Rhys already sidelined, Tom's untimely pre-season injury has left us light at scrum half, having only a winger or untried youngsters as cover," Andy Lloyd, Ospreys' rugby operations manager, said in a statement.
"With that in mind we felt it was crucial that we acted swiftly, and in Phil we have someone who has impressed at international level and who we believe can come in at short notice and do a good job for the region."
Mack, a 27-year-old from Victoria, has won 15 caps for Canada and is a former captain of the national sevens team.
"This contract comes as a reward of Phil's consistent play over the summer in the Pacific Nations Cup and in the Rugby World Cup qualifiers against U.S.A.," said Steve Lancaster, Rugby Canada's high performance manager.
"Although it's a short-term deal, it's a great opportunity for Phil to experience professional rugby in the U.K. and it will give him exposure to potentially receive a longer contract."
The Ospreys play in the RaboDirect Pro 12 league.
