According to Adam Schefter, it's "at least two games." But when I read that I think Ndamukong Suh is going to get only a two game suspension for his stomp of Green Bay Packers OL Evan Dietrich-Smith. I was expecting only a one game suspension. Kevin Seifert pointed out that the Packers passing game improved after Suh was ejected, so this will impact the Lions playoff hopes.
And as a side note on the ejection of CB Pat Lee, the Packers didn't realize that Lee had been ejected until Jim Schwartz pointed it out to the refs. It's just odd that everyone missed it. I can't imagine the Packers were trying to find some advantage by keeping Pat Lee in the game.
