07:59 AM ET 06.29 | This time there were no arguments between Alex Smith and reporters, but Camp Alex II did have something in common with much of Part I. Michael Crabtree was on hand for the session but did not go through a full practice because of lingering concerns about his left foot. ... Today he arrived midway through the classroom session and then joined his teammates on the field. At first it appeared as if Crabtree would only watch from the sideline. But during warmups, he briefly left to get a new pair of shoes and then jumped in with teammates for some light warm-up work on the field. When the practice started, he hung close to the quarterbacks, charting plays. According to a teammate, the problem is Crabtree's left foot, which required surgery to correct a stress fracture prior to the 2009 draft.
