Three Indianapolis Colts listed as "questionable" on Friday's injury report did not travel with the team to Denver and have been ruled "out", ESPN.com's Paul Kuharsky reports.

Linebacker Clint Session, defensive back Brandon King, and wide receiver Pierre Garcon will all miss Sunday's game with hamstring injuries.

Garcon's absence is likely the biggest loss for the Colts, and to fill the void, the Colts signed undrafted rookie wide receiver Blair White off the practice squad. As one of three healthy receivers on the 53-man roster, White, who led the Colts in receiving during the pre-season, is likely to dress against the Broncos.

Second-year linebacker Ramon Humber has been "waived/injured".

2010 seventh-round pick Kavell Conner is once again expected to replace Session in the starting lineup at weak-side linebacker. Conner started his first NFL game last week against the New York Giants, posting the first five tackles of his NFL career.
