Tyson Chandler has received an official offer from the Warriors worth more than $60 million over four years, according to a source.

Chandler is an unrestricted free agent after spending last season with the Mavericks.

In order to sign Chandler, the Warriors will likely need to amnesty Andris Biedrins.

Golden State is hoping to receive a commitment from Chandler on the first day of free agency on Friday.
