The Carolina Panthers could be down another offensive lineman for Sunday's game against the Minnesota Vikings.
Guard Amini Silatolu, who was expected to move to right tackle after Nate Chandler went down with a knee injury, did not practice Friday due to knee swelling, as reported by Jonathan Jones of the Charlotte Observer.
It is the second consecutive practice Silatolu has missed, though there is no word yet on how serious the injury is. He was held out of the Panthers' Week 11 loss to the Atlanta Falcons with the same issue.
