The most serious was Walker, who dislocated his right elbow and will be lost for at least a month. Walker was hurt while covering Daryl Jones in a one-on-one drill.
"When I was going for the breakup, my arm was wrapped around his arm," Walker said. "My arm was hyperextended and he fell on my elbow, which dislocated it."
Babers is likely out for a week after tweaking his hamstring, while Peterson practiced only on a limited basis following a slight groin injury.
