Warriors coach Don Nelson believes the team will pick up the fourth-year option on the contract of forward Brandan Wright.

The option is worth less than $3.4 million for the 2010-11 season and means Wright will be a restricted free agent in 2011-12.

Team sources told the San Francisco Chronicle that nothing is official yet, but barring an injury the Warriors will exercise the option by the NBA's Oct. 31 deadline.

"I've always liked him, but it takes about two years before most rookies fill out a little bit and become a factor," Nelson said of Wright. "This is his third year, and I think it's a big step for him."
