Sainey Nyassi has been put on the disabled list due to his hamstring injury. He's now out for at least 6 games (seems to be 6-8 weeks) but the Revs can sign a replacement player.
I have to wonder if the idea is to bring in his eventual replacement. I doubt it, since that's kind of shady, but it is certainly a possibility. If that was the case, Nyassi would come off the list and get cut or traded once healthy.
