On Sunday, Judd Apatow took to Instagram to share a picture of a large group of stars gathered at Shandling’s home for a game of basketball – a sport the star of The Larry Sanders Show was a big fan of and often played at home with his friends. “One last game of basketball at Garry’s house to say goodbye,” Apatow, 48, captioned the picture, which featured several stars, including Jeffrey Tambor, Bill Maher, Kathy Griffin, Sarah Silverman, Ryan Philippe, Jesse Bradford, Breckin Meyer, Kevin Nealon and more. Filmmaker Alex Richanbach reposted his own shot of the group, writing: “One last Sunday Game at Garry’s.” “Adam McKay put it best, ‘Garry’s 3rd show was putting together this family of friends,’ ” Richanbach added. “Not too bad to have three masterpieces in one life. I’m so grateful to have such a great group of friends that all loved Garry so much. We’ll miss you forever.” Added comedian Suli McCullough: “For the past 12+ years, I’d spend my Sunday’s playing basketball at Garry Shandling’s. It was one of those private amazing activities that I’d always look forward to. Yesterday, we played one last game in his honor. #ripgarryshandling #garryshandling #sulistrong.” Silverman, 45, shared old photos of her playing ball with Shandling in an emotional tribute: “We lost our most brilliant comic mind & I lost the most generous loving mentor & friend. Who will I guard?” she wrote. “I’m 1 of many comics that can say it – he made us feel special til we believed it. My teacher my friend my Garry,” she added. Over the weekend, a few of the stars also gathered for dinner at Craig’s in Los Angeles to honor the late comedian. “A bunch of fans of Garry Shandling who were lucky enough to become friends of Garry Shandling,” Bradford captioned a picture of the group at dinner on Instagram. “RIP brother I don’t think you even realize how much you will be missed.” Meanwhile, the investigation into Shandling’s death is still ongoing, and Assistant Chief Coroner Ed Winter tells PEOPLE from Los Angeles the cause of death has been “deferred pending additional tests.” PEOPLE previously confirmed that Shandling collapsed while on the phone with 911 before being taken to St. Johns hospital in Santa Monica, California, where he died Thursday. Winter told PEOPLE Friday that Shandling spoke to a doctor friend before his death, complaining about the discomfort in his legs and shortness of breath. Now Winter says that, because Shandling had not been to his primary physician in over a year, the doctor could not sign the death certificate. The coroner’s office will “issue a deferred death certificate so the family can proceed with funeral arrangements,” Winter adds. Winter says “it appears that it was a heart attack,” though a final decision is still pending as they are awaiting the toxicology report.
