Natick will try to do something it hasn’t done since 2009 — beat Walpole.

This was supposed to be a battle between undefeated Bay State teams. Instead the Rebels (9-0), one of nine unbeaten teams in Eastern Massachusetts, will travel Friday to Natick to play a team trying to bounce back from a stunning, 40-34 loss to Wellesley last Saturday. If Walpole wins, it clinches the Bay State Herget title and a playoff berth. If Natick wins, it must beat Framingham on Thanksgiving to clinch a berth or hope Walpole loses to Weymouth on Thanksgiving.
