The two parties worked out a seven-year contract worth $37.295 million with a $7.5 million signing bonus. However, there are $7.25 million in "de-escalators" tied to workout requirements and weight restrictions, a source told Comcast SportsNet Bay Area's Matt Maiocco on Wednesday.
For the final five years of the contract, $1.25 million is annually dependent on Davis' participation in offseason workouts and his weight, Maiocco reported. The exact weight numbers Davis needs to maintain weren't made available.
Davis is listed at 323 pounds, and there were questions about his work ethic coming out of college. He has proved otherwise in three NFL seasons, developing into one of the top right tackles in the league. The 49ers apparently want to keep it that way.
