(AP) -- Jonas Valanciunas has been the big man in the middle of the Toronto Raptors' rise for the last three seasons.
Now he has the big contract to match.
The Raptors and Valanciunas announced his four-year contract extension Thursday. The deal is worth $64 million, a person with knowledge of the contract told The Associated Press. The person requested anonymity because the team is not publicly announcing the terms, which were first reported by Yahoo Sports.
