I can't see it unless he really can't go (which might be the case now). He's already played injured for most of the season. I think the real question is his effectiveness, which was fine in the 49ers game but wasn't last night. Why can't you see it? It's only been three games and he's seemingly on the verge of falling apart. There is a lot of time left this year and missing one game now could go a long way to preserving him for a potential playoff run. Marshall was not effective for the entire SF game, he was worthless for a while. He had 3 TDs in SF, including one of the best he's ever had. He was plenty effective in that game, in spite of having a low yards total.
