MANKATO -- Vikings center John Sullivan is back on the practice field and in pads for this morning's training camp practice after missing the past two days because of an injury to his right calf.
Cornerback Benny Sapp, however, isn't taking part and will miss a fourth consecutive practice because of the effects of cramping and dehydration he suffered from during the Saturday morning practice. That will give Lito Sheppard plenty of reps at right corner in today's opening practice and Asher Allen probably will see most of the time with the first team at nickel.
