Colts TE Dallas Clark has been placed on injured reserve after undergoing wrist surgery, officially ending his 2010 season, while P Pat McAfee was put on the reserve/club suspension list following an arrest on Oct. 20.
To fill the roster spots, the team signed CB Chip Vaughn and P Jeremy Kapinos.
Vaughn was a fourth-round pick of the Saints in 2009, but did not appear in any games with the team and was released by New Orleans at the end of training camp. He then signed with the Eagles' practice squad before being signed by the Colts.
Kapinos was the Packers' full-time punter a year ago and has also seen time with the Jets. He has a career average of 42.8 yards per punt.
