The Bulls need to replace Derrick Rose at point guard for at least the first part of next season.
The latest candidate to emerge for a fill-in spot is former Golden State guard Nate Robinson.
It was reported in several places that Robinson had agreed to join the Bulls, but a league source maintained Monday afternoon said a deal was not yet official.
Robinson is best known for being a three-time winner of the slam-dunk contest. He stands just 5-feet-9 but has one of the highest vertical leaps in league history.
He broke into the NBA with New York in 2005 and averaged 17.9 points for the Knicks in 2008-09.
A year later Robinson was traded to Boston, then went to Oklahoma City in the Kendrick Perkins deal.
He played 51 games for Golden State last season, averaging 11.2 points and 4.5 assists in 23.4 minutes.
With 12 players already under contract, the Bulls can sign additional players using only the league's minimum salary.
Robinson certainly would add some noise to the Bulls' locker room. His personality is loud and outgoing, quite a difference from most of the current Bulls.
He is familiar with Bulls coach Tom Thibodeau, though, playing for him in Boston during a portion of the 2009-10 season. Robinson is good at driving to the basket, but he has averaged a relatively meager 2.8 assists over his career.
He played cornerback on the football team during his college days at Washington.
