INDIANAPOLIS (AP) — Colts coach Jim Caldwell changed the training camp script Wednesday.

He shortened the morning practice and ran a new drill that he calls 30-30 — 30 plays for both the offense and defense.

It was the most noticeable change Caldwell has made to the camp routine since replacing coach Tony Dungy. The move also came on a day that Caldwell will hold his first night practice at Rose-Hulman Institute of Technology.

Caldwell said the Colts would do more work Thursday night.
