Former Australian Open champion Mats Wilander is out of hospital after a fall that lacerated a kidney.

Former world No.1 Mats Wilander has been released from hospital following treatment after he fell and lacerated a kidney, his company says.

In a Facebook posting, Wilander on Wheels (WOW), which runs tennis clinics, gave an update on the condition of the Swede, a commentator for Eurosport.

"To give everyone an update on Mats' condition ... Mats has been released from the hospital and is recovering at a hotel," the message, posted on Thursday, said.

"In the end, Mats received a blood transfusion of three units of blood (a little less than a litre) and accepted the transfusion well! He is healing properly and hopes to be on his feet shortly for GAME SET MATS!

"He will not be playing tennis for at least one month. WOW's schedule for the month of February will need to be postponed. WOW is hopeful to resume operations sometime in March.... Thanks for everyone's concerns."

Wilander was taken to hospital in Melbourne on the eve of the Australian Open after a fall in his apartment on Saturday in which he lacerated one of his kidneys, causing internal bleeding.

Wilander, 47, won seven grand slam singles titles, including three Australian Open titles, in a glittering career.
