Defensive end Travon Walker suffered a wrist injury early in the game and was eventually ruled out. On the other hand, Murray's absence most definitely hurts the secondary. This is a long-winded way to say that the Jaguars probably won't reveal just how serious Travon Walker's and Eric Murray's injuries are. On the other hand, Murray's injury could test Jacksonville's depth at safety. Ultimately, the Jaguars just suffered a couple injuries that could turn out to be massive blows, if not against the 49ers, probably in future games.
