If Tisha B'Av falls on Motza'ei Shabbat and one forgot Havdalah in Shemoneh Esreh, must one repeat?

ShabbatPrayerShemoneh Esreh

Synopsis

When Tisha B'Av falls on Sunday, Havdalah over a cup is delayed until after the fast. If one forgot Havdalah in tefillah, one need not repeat because the cup-Havdalah after the fast serves as the fallback.
