Toronto Raptors power forward Chris Bosh will be signing a contract extension that mirrors the shorter-than-expected deals signed by LeBron James and Dwyane Wade, ESPN.com has learned.

Bosh, according to NBA front-office sources, has elected to sign a three-year deal with the Raptors worth an estimated $40 million-plus, with a player option in the summer of 2010 to extend the deal for a fourth season and take the value of the contract into the $60 million range.
