Colts signed RB Mike Hart, TE Colin Cloherty, WR Samuel Giguere, WR John Matthews, OG Jaimie Thomas, and WR Taj Smith to their practice squad.
They still have two spots left. Hart has been banged up since the Colts made him a sixth-round pick in 2008. He is a better runner than No. 3 back Chad Simpson, though, and could get another shot with the big club later on.
