The biggest development Thursday was the return of receiver Mitch Mathews, who has been out of contact drills since undergoing surgery for a hernia two weeks before camp started.
In fact, Mathews caught a touchdown pass from Taysom Hill on his first play.
"It is just part of his normal progression," Mendenhall said of Mathews' return. "This is day three or four with partial practice. So, the trainers are working through that. There's a certain percentage each day, and he gets it, and then I just look out there and either I see him or don't see him.
