Due to ongoing issues with his knee, Madrid's Kaka will not be able to play for another two weeks.

The Brazilian, who underwent surgery after the World Cup last summer and has been sidelined for half a year, returned to the field in January, but the problem reappeared during a duel with La Coruna's "Deportivo."

Kaka will miss the Champions League round of 16 second leg match against "Lyon," as well as the Madrid derby against "Atletico" on March 19th.
