The Indianapolis Colts were not exempt from injury during 2013 training camp, and they have to roll with the punches. The game of football is a chess match, and when a piece goes down, that piece has to be replaced.
The offensive line was already a sore spot for the Colts, and there has already been injury issues to that area in practice. For that exact reason, Indianapolis made many efforts to load up the offensive line. For some reason, the Colts seem forced to shuffle their offensive line week after week, but right now they have bodies to spare.
Aside from signing center Thomas Austin, and waiving linebacker Scott Lutrus, the Colts kept moving more pieces into place. The Colts also signed guard Danous Estenor, and waived guard Robert Griffin.
