Was there any reference to the Russian who escaped in the woods in the Sopranos?

From the 12/5/2012 Slate article David Chase Doesn’t Care About the Russian:

“Who gives a shit about this Russian?” David Chase says. The creator
of The Sopranos has never understood his audience’s fascination with
Valery, the Russian mobster who disappeared in the legendary “Pine
Barrens” episode. It was a one-off story that needed no closure, Chase
says now. He recalls thinking, “We did that show! I don’t know where
he is! Now we’ve got to go and figure that out?!?!”

Terence Winter,
who wrote “Pine Barrens” and many of the series’ other memorable
outings, agreed with the fans on this one, much to Chase’s
frustration, and kept pushing his boss to add a coda to that story in
The Sopranos’ final season. They finally hit on an idea everyone would
be happy with: Tony and Christopher pay a visit to the local Russian
mob boss, where they find Valery sweeping the floor, not recognizing
Christopher thanks to a traumatic brain injury suffered when Chris and
Paulie were shooting at him. (It would be explained that a local Boy
Scout troop found him with part of his skull missing, and saved his
life.) At the last minute, Chase changed his mind, and he recalls a
despondent Winter insisting, “God, you’re making a huge mistake
leaving that on the table!”

It's non-canonical, sure, but we'll take what we can get.
