"There were two headlines from Day 1 of Camp Alex II: The first is that receiver Michael Crabtree was on hand for the session but did not go through a full practice because of lingering concerns about his left foot. The second is that rookie quarterback Colin Kaepernick was a full participant in the practice and, for the first time in a team session, showed off the arm strength for which he was noted prior to the draft.

To get you up to speed on the Crabtree story - the receiver attended the 49ers' previous minicamp but only took part in the June 6 practice. According to teammate Josh Morgan, Crabtree suffered sore feet during that Monday session after practicing in new shoes. He attended the morning classroom sessions Tuesday-Thursday but left when they were over and did not go out to the practice field.

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."
