Sophomore Meg Colligan, who filled in for Belisle at sweeper against B.C., will be able to move back to her normal forward position.
"We'll have Amy back which will be good because Meg can put the ball in the net," Caples said.
Harvard will need all the help it can get against the solid Tiger defense:
Before it conceded two goals to Penn, Princeton had only been scored upon once in four Ivy contests.
The Tiger wall is led by netminder Melanie Orpen who has recorded three shutouts in the Ancient Eight and boasts a 0.72 goals-against average.
On defense, the Crimson will have to keep its eye on Princeton freshman Lisa Rebane. Rebane leads the team with three goals and three assists, and should provide most of the Tigers' offensive fire today.
