Melbourne - Former world number one Yevgeny Kafelnikov has put on more than 20kg and retired from tennis, said Marat Safin at the Australian Open on Monday.
Safin teased reporters that his Russian Davis Cup team-mate Kafelnikov, whose career has been in limbo since October, would not be returning.
"Guys, he quit," smiled Safin, who beat American Brian Vahaly 6-2, 3-6, 6-3, 6-4 in the first round at Melbourne Park.
"Finished. You will not see him anymore. He is 105 kilos now. It's a lot of kilos, huh?"
Kafelnikov won the 1999 Australian Open and the 1996 French Open titles but the 29-year-old has been evasive about his future plans.
