Australia back Christian Lealiifano has been diagnosed with leukaemia and is undergoing treatment.

The 28-year-old, who has won 19 caps for the Wallabies and plays for Brumbies, has been found to have the disease following tests in hospital after a short illness.

"At the moment it's just a matter of ensuring Christian receives the best care and support he can at this time," Brumbies chief executive Phil Thomson said in a statement on the club's official website.

"He is one of the most respected players within this group and this news has come as a huge shock to all of our players, coaches and staff.

"Everyone knows that Christian is an amazing young man, an important member of this team and of the Canberra community.

"Our thoughts and prayers are with Christian and his family at this time."

Lealiifano played in all three Tests against England earlier this summer and has recently celebrated the birth of his first child.
