49ers injury report: A.J. Jenkins, Kassim Osgood join potential training camp walking wounded at wide receiver

The San Francisco 49ers have wrapped up practice No. 5 of training camp, and the wide receiver position continues to deal with some injury issues. Matt Maiocco has the first post-game practice report looking at injuries, and the team is dealing with a variety of nicks and dings.

The beat writers reported that A.J. Jenkins and Kassim Osgood both sat out the main practice session after warm-ups. The early reports are hamstring strains, but we don't have any specifics beyond that. Kyle Williams also sat out practice today, which was his second straight missed practice. The two practices off sandwiched a team day off, so Williams has sat for three days. Reports were that he had his hamstring checked out on Saturday.

Given how quickly hamstrings can become chronic issues, so it makes sense early in camp to get the guys off the field. Ideally they'll be back sooner rather than later, but why risk a full blown tear, or some other problem that can be avoided with a little extra rest. The wide receivers need to work with Colin Kaepernick, but for now we just have to wait.

Jonathan Goodwin and NaVorro Bowman also sat out practice. In the post-practice press conference, Vic Fangio said he was just working through a little something. Again, no reason to rush things so early in training camp.
