There has been some uncertainty as to whether three of the team's biggest names will attend the voluntary offseason program.

Warner, 28, is a four-time first-team All-Pro and a four-time Pro Bowler. He posted 100 or more tackles in all seven of his NFL seasons, registering 131 tackles (five for loss), two interceptions, seven passes defensed, four forced fumbles and a sack last season.

With his contract talks supposedly going in a “good direction,” Brock Purdy joined his 49ers teammates Tuesday for the start of the voluntary offseason program.
