Conley said Wednesday after shoot-around that Pera called him Tuesday to alert him to the Grizzlies' intentions.
Gasol declined to share details of his conversations with the Grizzlies owner, saying he considers those private. Gasol, who can opt out of his contract this summer, says he had not asked to be traded.
Conley and Gasol are the Grizzlies' remaining cornerstone players having played their entire careers with Memphis. ESPN.com reported late Tuesday afternoon that the Grizzlies were open to trading the veterans.
