Sunday's San Francisco 49ers news carried a very familiar training-camp theme: early August injuries are already part of the conversation. As the team continues its summer work, health remains one of the biggest storylines around the roster.

One of the clearest updates from practice was the absence of top pick De'Zhaun Stribling, who is dealing with hamstring tightness. Even a minor issue stands out at this stage of camp, when teams are trying to build continuity and avoid setbacks before the preseason schedule moves along.

There was also a positive headline for the 49ers offense. Deebo Samuel reportedly showed up in really good shape and made an impression in his first practice. That is an encouraging sign for San Francisco, especially when established playmakers are expected to set the tone early in camp.

Taken together, the latest 49ers update reflects the usual balance of August football: excitement over standout performances mixed with concern over new injury news. For San Francisco, that push and pull is already shaping the start of camp.
