The San Francisco 49ers are navigating contract negotiations with franchise quarterback Brock Purdy and star tight end George Kittle as they kick off their offseason program. Although no long-term extension is finalized for Purdy, he actively participated in the voluntary workouts, indicating a cooperative atmosphere despite the lack of a deal. Purdy, eligible for an extension for the first time, aims for a substantial salary increase, possibly exceeding $50 million annually. Meanwhile, Kittle, entering the last year of his contract, is reportedly interested in retiring with the 49ers but is absent from this phase of workouts, a common occurrence for veteran players in similar situations.
