Puk (shoulder) will play catch Friday, Susan Slusser of the San Francisco Chronicle reports.
Puk's shoulder issues returned earlier in the week, leading to him being placed on the injured list with a shoulder strain Monday. He underwent a cortisone injection and is already ready to throw again, which is certainly a good sign for his eventual return to action. He's expected to miss at least two weeks, with Daniel Mengden filling his rotation spot for now.
