The annual Oscar Knox charity golf competition teed off with a host of sporting stars taking part in the annual charity fundraiser.
Among those taking part is Belfast two-weight world champion boxer Carl Frampton along with fellow boxers Paddy Barnes and Michael Conlan.
Frampton auctioned off a chance for three lucky golfers to play alongside him on the day in a four ball.
Carl Frampton was among Oscar's biggest supporters and he has joined forces with the event to make it even more special.
Also starting at the tournament at Fortwilliam Golf Club in Belfast are snooker player Mark Allen and golfing wonder-kid Tom McKibben.
The annual golf tournament is in memory of Oscar Knox, the little boy from Mallusk, Co Antrim, who captured the hearts of people around the world as he fought a rare form of cancer.
Oscar died two years ago after a brave battle against high-risk neuroblastoma - a rare and aggressive childhood cancer.
He was diagnosed in November 2011 and his parents Stephen and Leona went public in a bid to raise awareness and funds for Oscar's care.
The fundraising drive helped cover the cost of taking Oscar to America for cutting-edge treatment not available in Northern Ireland.
On Friday there will be 18 holes of golf, a BBQ, auction and evening entertainment.
