I wondered that last night myself. I haven't been watching today's game at all closely, but I saw a bit of him in the booth with Selleck. I guess that could well have been set up prior to the season, too. I assume it would be cheaper to bring him back for it since they would probably have to pay him even if they reassign it.
I did a DuckDuckGo search on his name and got a link to a LinkedIn post he made. it's since been deleted, but DDG must have it still cached.
there's no date on it, but I imagine it was from shortly before the season, after he was let go from full-time work.
