The Colts are confident that Campbell (abdomen) will be available for Sunday's game against the Rams, despite him being listed as questionable on the official injury report, Adam Schefter of ESPN reports.
Schefter adds that the team wants to test Campbell in pre-game warmups before making a final decision on his status. If active Week 2, Campbell would likely join Michael Pittman (ankle) and Zach Pascal as a fixture in three-receiver sets.
