I don't know if I am necessarily surprised the team placed Morgan on injured reserve, but it is still disappointing. Morgan really seemed to be taking a step forward as a wide receiver and was a huge part of this offense both as a pass catcher and as a blocker. He is a big, physical guy who really could do just about everything you asked of him in this offense.
It will be interesting to see how the offense handles this over the weekend. I posted the tight end breakdown earlier today and I stick with my belief that Delanie Walker could be a big difference-maker this week. While it is disappointing to lose a big, physical receiver like Morgan, the good news is the 49ers are closing in on getting back another physical receiver in Braylon Edwards. Injuries suck, but there is a silver lining for this season.
Best of luck to Joshua in his rehab back. He is actually a free agent after this season and it will be interesting to see what the market is like given this season-ending injury. He is a guy I really hope the 49ers re-sign.
