There are three more games on the NHL regular season schedule for the Chicago Blackhawks, and two of them are at the United Center — beginning tonight against the Minnesota Wild. These could be the final two home games in the career of captain Jonathan Toews. ‘‘For myself, I’m taking it as if these are my last games in Chicago,’’ Toews told Ben Pope in Seattle on Saturday night. While he has not yet completely ruled out a return next season — in Chicago or elsewhere — the finality of this week is very real for the longest tenured captain in Blackhawks’ history and the fans who have cheered for him for almost two full decades. Here’s hoping the United Center is back at a standing room only level to say thank you tonight and on Thursday.
