Buffalo Bills receiver David Nelson was relieved to learn he will miss only a few days of practice after being diagnosed with a strained tendon in his right leg. Nelson provided the update after missing practice Sunday, a day after he was hurt. He walked with a slight limp, and was wearing a wrap around his injured leg. Nelson initially feared the injury was worse after he was pushed over during a team drill and defensive end Mario Williams rolled up on his leg. Buffalo coach Chan Gailey expects Nelson to miss between four and five days. Source: ProFootball Weekly
