British and Irish Lions coach Ian McGeechan said he may take two weeks to name a replacement for scrumhalf Tomas O'Leary, who broke his ankle and will miss the tour to South Africa.

O'Leary was injured in a collision with David Wallace and taken to Cork University Hospital in Ireland in Munster's 29-10 win over Scarlets in a Magners League match on Friday.

The accident occurred only three days after the Ireland back was named to his first Lions squad.

With the European club semi-finals next week and the English semi-finals the week after, McGeechan wanted to watch possible replacements in action.

"I'm obviously desperately disappointed for the player but we'll take our time and keep our eye on things," McGeechan said on Saturday. "I'm not looking to name a replacement for 10 to 14 days. There's some rugby to watch and I'll take my time."

In contention were Scotland captain Mike Blair, 2005 Lion Dwayne Peel of Wales and Danny Care of England.
