They could play the game on Wednesday, move the Sunday games for both teams to Monday or Tuesday. Then have the playoff games on the following Monday.
Since they will have another playoff game on that Monday anyway.
Yes it makes for short weeks, and give the opponent an extra days rest. But what else can they do beside shifting every thing back. a week. Then their opponent will have an extra week of rest.
From playing Wednesday, then on Monday, would be no different than playing Sunday, then again on Thursday.
