Back in October I was at a dinner with a group and P.K. was among the guests. He mentioned that evening that the Canadiens were planning on "honouring" both him and Markov together at some point during the season. He said they reached out to him right after he announced he was retiring and the way he was talking the plans remained very much in flux at that point.
When the official announcement came, there was no mention of Markov and I assumed it was because of the political issues and Markov being in Russia, but from what he was saying the organization very much wanted to show Markov the same respect.
He even made a joke about a logo with a 76 where the 6 would spin to become a 79, then back to 76, etc.
