The Bulls offered a one-year deal to Fabricio Oberto, according to a report.

Oberto retired last season, but has been cleared to return to action with an aim to play in the 2012 Olympics.

"The first proposal made by Bulls was for a workout, but the offer was turned down. Bulls want him as backup of Joakim Noah. Now the final decision belongs to Fabricio" said his agent Carlos Prunes.
