Anthony Castonzo (knee/ankle) to undergo season-ending ankle surgery

Indianapolis Colts left tackle Anthony Castonzo will undergo season-ending ankle surgery.

Fantasy Impact

This is a big blow for the Colts fading playoff aspirations and will also have an effect on the running game for Week 17, and any potential playoff DFS contests. Castonzo is one half of a dominant left side of the Colts offensive line, along with All-World left guard Quenton Nelson. The Colts have an easy Week 17 date with the Jacksonville Jaguars but will need to secure a win and look for some help elsewhere to make the Philip Rivers move produce to expected results.
