dnd 5e – Does Ranger Monster Hunter’s Slayer’s Counter works on saves to maintain concentration?

From the sage advice compendium:

Blockquote
Does a Monster Slayer ranger’s Supernatural Defense
feature apply if a creature damages the ranger, thus
causing the ranger to make a Constitution saving throw
to maintain concentration on a spell? Yes.

Since the Supernatural defense works for concentration, does the Slayer Counters works as well?
