Phillies first baseman Ryan Howard will be sidelined for six to eight weeks after an MRI revealed that the pain in his knee was actually a torn meniscus, which will require surgery.

The Phillies placed Howard on the disabled list on Saturday due to left knee inflammation, something that has been plaguing the slugger since May. This came a week after Howard received a cortisone shot in the same knee.

You may recall that Howard received a cortisone shot in his foot not long before he ruptured his Achilles' on the final play of the season-ending game against the Cardinals in the 2011 postseason.

Howard was hitting .266 with 11 home runs and 43 RBI this season before heading to the DL, but has struggled even more than usual against lefties, hitting just .173 against them this season.
