MSNBC’s Chris Matthews has been off Hardball this week as he recovers from a bout of pneumonia. Matthews was felling sick last weekend but went to work Monday. He later went to the doctor and was diagnosed with pneumonia. David Shuster has been filling in this week and a special edition of Hardball tomorrow night will be anchored by Andrea Mitchell. We’re told he’s following doctor’s orders and resting up so he’ll be ready for the conventions.
