Roger Federer will not play Davis Cup

Federer will not be playing in the upcoming (mid-February) Davis Cup match against Australia set in Geneva, Switzerland. This is the same match that Lleyton "Rebound Ace" Hewitt will not be playing in. The odd thing is that several news stories are citing Federer's ankle injury as the reason:

Federer has been struggling since October to overcome a right ankle injury and has been excused playing next week by Swiss captain Severin Luthi.

Now, I don't much care whether or not he plays - but someone could at least provide a legitimate reason. He sure didn't seem to be "struggling" with an ankle injury in the AO. Poor baby.
