Irsay — Mr. Twitter — tweets the sobering but not shocking news that Manning, who will not play Sunday for the first time in his NFL career, will be out “awhile:”

“NFL Season opens 2nite!We had a good practice yesterday and r guys r fired up 4 the season.#18′s out for awhile,but compete,we will/BELIEVE.”

On Wednesday night, Irsay shot down an Indianapolis radio report about his quarterback, tweeting that Manning has not had another procedure on his neck. “Peyton didn't have a medical procedure last sunday,we'll have more info 2 add clarity 2 situation soon.”

The Colts have not said whether Manning will travel with the team to Houston for the season opener Sunday against the Texans. Until the Colts add that clarity, feel free to debate exactly what “awhile” means.
