After debuting them last season, the Giants will again wear their alternate slacks for two games, a changeup from the traditional gray. The games -- both at home -- will be against the Indianapolis Colts in Week 9 on ‘Monday Night Football’ and two weeks later against the San Francisco 49ers. The usual home blue jerseys will be worn.
