Tom Thibodeau traveled on Wednesday to Derrick Rose's offseason base outside Los Angeles to witness Rose's workouts less than a month before training camp starts.

Rose is set to travel to Asia Sept. 4-16 for his second shoe promotional tour this offseason.

Rose has increased range on his jumper and has been working extensively on his left-handed floater.

Rose is expected to attend the Chicago Bulls' training camp in late September after missing last season following knee surgery.

With no NBA out clause, Ivan Johnson has signed a one-year contract with the Zhejiang Golden Bulls of the Chinese Basketball Association, a league source told RealGM.

Johnson, the 6-foot-8 free agent forward, received interest throughout NBA free agency, and his four finalists were the Los Angeles Clippers, New York Knicks, Indiana Pacers and Chicago Bulls, a source said. He decided to accept a more lucrative deal in China – where he spent the 2011 season – instead of continuing to wait for an organization to enhance its offer.

Johnson also is hoping to take advantage of China’s shorter season and return to the States late in the NBA season, when teams will deal with possible injuries and look to add pieces.

There remains strong interest in Johnson, and the 29-year-old took a deal for one season in order to return next year. RealGM first reported on Aug. 16 that Johnson had started to seriously consider leaving the NBA for offers in China and Italy.

Johnson averaged 6.5 points and 3.9 rebounds over two seasons with the Atlanta Hawks, carving a role as an active, tough big man after bouncing around in his basketball career.

Ronnie Brewer considered returning to the Chicago Bulls or Utah Jazz before signing with the Houston Rockets in unrestricted free agency.

"They play my style," Brewer said. "Dwight Howard is a defender, but can get up and down the court."

Brewer played with the Bulls for two seasons and was the Jazz's draft pick in 2006.

Free agent center Dexter Pittman has accepted an invitation to the Chicago Bulls’ training camp, a league source told RealGM.

Pittman’s camp deal will be non-guaranteed, giving the 6-foot-11 big man an opportunity to battle for a spot on the regular season roster.

Pittman played four games for the San Antonio Spurs’ summer league team, averaging seven points, six rebounds and two blocks and impressing people in Las Vegas with his elevated fitness and slimmed physique. The Bulls have been searching for a frontcourt player to round out their roster, and they currently have 12 guaranteed contracts.

A 25-year-old, former second round pick, Pittman was an NBA champion with the Miami Heat in 2012. Pittman, who averages 2.4 points and 1.8 rebounds over three seasons, finished last season spending seven games with the Memphis Grizzlies.

Sportando first reported Pittman’s decision to appear in training camp for Chicago.

Anthony Tolliver has been offered a one-year deal by the Charlotte Bobcats at the veteran's minimum.

Tolliver has also received interest from the Chicago Bulls and Utah Jazz.

Tolliver spent last season with the Atlanta Hawks.

Jimmy Butler admitted Chicago and Miami have a dislike for each other, and he believes that intensifies the Bulls' hopes not to let the Heat three-peat.

"That rivalry, it's crazy," Butler said. "They're the back-to-back champions and when you think three-peat, you think Chicago so we can't let that happen."

Butler said the Bulls are not looking forward to watching the Heat receive their championship rings on Oct. 29, when the two teams are expected to open the season in Miami.

"I don't think anybody wants to watch that on our team so we won't pay too much attention to it," Butler said. "They deserved it. They won a championship, definitely, but they got to deal with the Chicago Bulls for 48 minutes coming out right after that, they get their rings."

Antawn Jamison has received free agent interest from the Chicago Bulls, Los Angeles Clippers, Memphis Grizzlies and Charlotte Bobcats, according to a report.

Jamison wants to take time in making the best decision for himself, instead of rushing as he did last offseason.

Jamison believes he has two seasons left to compete at a high level.
