Logic Masters Deutschland e.V.

With the American football season starting up (collegiate games this week and the NFL next week), this puzzle is dedicated to many fans' least favorite part of the game: the referees making questionable if not outright terrible calls.

Rules:

Normal Sudoku rules apply.

Kropki Dots: Cells separated by a white dot are consecutive. Cells separated by a black dot have a 2:1 ratio. Not all possible dots are necessarily given.

Penalty Flags: Nine cells in the grid are disobeying the Kropki dot rules, and have had a yellow penalty flag thrown at them. There is one flagged cell in every row, column, and 3x3 box. The flagged cells form a set of the digits 1-9. Flagged cells must not obey any given Kropki dots they are connected to. For example, a flagged 2 cannot connect to a 4 via a given black dot. Note that a flagged cell does not necessarily need to be connected to any given Kropki dots.
