"That ship has sailed," said Battier, 37. "The playing ship has left the port."
Battier played 13 NBA seasons with the Memphis Grizzlies, Houston Rockets and Miami Heat before retiring after the 2013-14 season.
He spent part of his day having coffee with general manager Sam Hinkie. He also attended that night's game with the Atlanta Hawks. Battier was scheduled to leave Philadelphia on Friday.
"Any time you can get somebody that's played that amount of NBA games and handled himself with that professionalism and class and intellect," said Brown, "you always want to say, 'What do you think?' And we learn.
"What that means down the road as far as a further relationship, who knows? But he is here for that reason."
There were plenty of reunions in Thursday's matchup. Elton Brand, now a Sixers reserve, played the last two seasons for the Hawks. Atlanta shooting guard Kyle Korver spent his first four-plus seasons as a Sixer. Brown and Hawks coach Mike Budenholzer were assistants with the San Antonio Spurs. Atlanta forward Tiago Splitter played under both coaches for the Spurs. Sixers guard Nik Stauskas and Hawks guard Tim Hardaway Jr. were teammates at Michigan. And Atlanta assistant Taylor Jenkins attended Penn.
