Here is a look at some of the top NBA rumors for Sunday, July 12:

  • It's been about 4.5 months since Wesley Matthews ruptured his Achilles tendon. Will he be ready for the start of the 2015-16 campaign? "Matthews jumped into his rehabilitation with remarkable vigor," wrote Eddie Sefko of the Dallas Morning News. "... His aggressive attitude toward doing more than doctors are asking is why he’s optimistic he’ll be on the court when the regular season opens in late October. Or soon thereafter if the recovery process demands it."

  • Isaiah Thomas underwent surgery on his shooting wrist 11 months ago. He recently had a second procedure on the joint, though it looks like he should be fine long before training camp gets underway. "Celtics guard Isaiah Thomas told the Globe late Saturday that he had surgery four weeks ago to remove a cyst in his left hand that was caused by a procedure last summer," wrote Adam Himmelsbach. "Thomas said that surgeons also 'cleaned out a few things' in the wrist during the surgery. He said he hopes to be 100 percent in 2 to 4 weeks."

  • The Sacramento Kings continue to tweak their roster, and the latest potential addition is Andrea Bargnani. "ESPN sources say Sacramento Kings are in advanced discussions with Andrea Bargnani and closing in on signing the former Knick," tweeted ESPN NBA Insider Marc Stein.
