Harrison: Week 9 predictions
Weatherspoon, second on the team in tackles and sacks, injured the ankle in Sunday's 30-17 win at Philadelphia.
The loss of Weatherspoon, a first-round pick in 2010, is a significant blow to the NFL's only undefeated team. He has had 10 or more tackles in four games this season after setting career highs with 127 tackles and four sacks in 2011.
