49ers’ Brandon Aiyuk reportedly at training camp — will he participate?

SANTA CLARA — Brandon Aiyuk is in the house.

After not appearing at the 49ers’ offseason program or mandatory minicamp, NFL Media reported Tuesday Aiyuk was in the building when the club reported to begin preparation for the 2024 season.

What is not known is whether Aiyuk will participate in the first practice Wednesday, or refrain from practicing until a contract extension is worked out. General manager John Lynch would not confirm Aiyuk’s presence although he expects him to be a 49er this year.
