San Francisco 49ers wide receiver Brandon Aiyuk has returned to practice as a spectator after a two-week absence due to a contract hold-in, which has entered its fourth week. Although he has not participated in training camp, Aiyuk was seen running sprints during practice, suggesting potential progress in contract negotiations. Aiyuk skipped the offseason program and is seeking either a long-term deal or a trade to another team. General manager John Lynch has expressed optimism about reaching an agreement with Aiyuk, although no deal has been finalized yet. Complicating matters, there are reports of a potential trade framework with Pittsburgh should negotiations fail. Amidst the uncertainty, Aiyuk's presence at practice and interactions with teammates indicate he remains engaged with the team.
