The family of former University of Memphis and NBA basketball  player Lorenzen Wright is pleading for his safe return after they say he mysteriously vanished a week ago.

Wright's mother, Debora Marion, told MyFoxMemphis.com the last time the family heard from her son was July 18, when he was visiting his children at his ex-wife’s house.

"She said she had laid down and woke up and he was gone in her van. Then she went back and laid down again. When she woke up again her van was back but he was gone," Marion said.

The last call posted on Wright’s phone record was made to his daughter that night, MyFoxMemphis.com reported.

Wright's sister, Adriane Harris, said Wright was last seen at a Memphis barbershop on July 19, when he had his hair cut.

The family filed a missing persons report with police, who said they don't suspect foul play.

Marion and Harris aren't ruling it out.

"If he wanted to be alone, he would have talked to someone in the family that I need it," Marion told MyFoxMemphis.com. "He has done this before, he would say I need a break and we understand that he needs a break and we wouldn't be worried because he told us he needed a break. But this time he just disappeared."

Wright played in college at Memphis and later for the Grizzlies as a pro. He last played in the league for the Cleveland Cavaliers during the 2008-09 season.

Harris did not say who she suspects would have harmed Wright or why, noting only he's always been reachable.
