The Colts have re-signed defensive tackle Ed Johnson after they waived him last season following a drug-related arrest. "We are giving Ed Johnson another opportunity to play for the Indianapolis Colts," Colts coach Jim Caldwell said in a statement Tuesday. "We dismissed Ed last year because he knowingly violated a team rule in the area of personal conduct. We consider every violation of a team rule or NFL policy on an individual case-by-case basis, and we evaluate a possible return to the team on that same basis." He originally signed with the Colts as a free agent in 2007 and started 16 games. "I would like to thank the Colts, especially [owner] Jim Irsay, for this second privilege to join the team," Johnson said in a statement. "I apologize to everyone for the situation I created last year."
