Manning suffered a thigh injury earlier this year against San Diego, and he just didn't look right after it.
"It's hung around but I felt like I tried to manage it," Manning said. "I felt like I could manage it. Completed some passes, won some games with it. It just hung around, just that one thigh, but there is nothing more to it than that."
Some inside the organization wonder. I talked to some Broncos players who said Manning was throwing more picks in practice in the past six weeks than at any other time. Before the game, some Colts veterans expressed to Broncos players that Manning's arm looked spent.
"You could tell something wasn't right," one Broncos player said of practice the past month. "He just didn't look like 18 out there."
