With players making a plea for peace, Italian soccer returned Sunday after an unprecedented one-week absence following the stabbing death of a fan in Genoa on Jan. 29.

All first-division sides swapped jerseys on the field just before kickoff and team captains read statements denouncing fan violence as part of a continuing campaign."We need to be united, not just us, but also the fans," AC Milan captain Franco Baresi said.
