Kaka's brother Digao has joined Serie B side Crotone on loan until the end of the season, say the club on their official website.
"Crotone communicates to have aquired the rights of Rodrigo Digao from Milan and he arrives on loan with the option to buy half of his rights," reads the note.
Digao left the Rossoneri last summer and joined Lecce in a loan deal that was set to expire in June 2010.
But that agreement was ended early and he returned to the Rossoneri, who have now sent him out on a second stint in Serie B.
Crotone also confirmed Somalian forward Ayub Daud has gone back to Juventus following his loan spell in Calabria.
