According to Marc Stein, regarding Kyrie Irving's injury status:

"I continue to be told there is no clear timeline for Irving's return. He tore his left ACL in the March 3rd game against the Kings and underwent surgery in late March. While the 33-year-old star has looked solid every time he's handled the ball in public appearances, the message conveyed to me over the weekend is that any timeline must still be described as 'fluid' (uncertain)."
