The Toronto Raptors signed restricted free agent forward Landry Fields to an offer sheet on Wednesday.

Terms of the deal were not disclosed but The Toronto Star reported earlier in the week that it is a three-year offer sheet worth about $20 million.

The Knicks have three days to match the offer and retain Fields' rights.

A second-round pick out of Stanford in 2010, Fields hasn't missed a game over his first two NBA seasons. He has career averages of 9.3 points and 5.4 rebounds in 148 games -- 143 starts -- with the Knicks.
