Video: Setting scene from 49ers minicamp

SANTA CLARA, Calif. -- Sunshine and temperatures rising into the 80s will greet the San Francisco 49ers as their mandatory three-day minicamp begins Tuesday afternoon.

Construction on the 49ers' new stadium, to be completed in time for the 2014 season, has changed the atmosphere at team headquarters. But with so many key players returning, including all 11 starters on defense, the feel at practice figures to be similar.

I'll be checking in with various 49ers coaches and players before heading to their minicamp practice at 3 p.m. PT.
