Peyton Manning got the cast off his left foot on Tuesday and will wear a walking boot until Friday.

Manning has not thought about his playing future beyond trying to get back on the practice field.

"This is when 'they' and 'sources' seem to show their heads a little bit . . . I haven't thought much other than about trying to get healthy," Manning said. " . . . I'm going to try to get healthy so I can try to get back. That's kind of where my focus is."

Brock Osweiler has played well for the Denver Broncos in place of Manning.
