A person familiar with the contract says Andrew Luck and the Indianapolis Colts agreed to a four-year, $22.1 million deal.

The Colts announced that they had signed the No. 1 overall pick Thursday. The person gave the terms to The Associated Press on condition of anonymity because the team had not released them.

The deal is similar to the one signed by Cam Newton a year ago and the one signed this week by Robert Griffin III. Newton, last year's top pick, has a four-year, $22 million deal with Carolina. And Griffin, who went No. 2 behind Luck, signed a four-year contract with the Washington Redskins worth $21.1 million, with a club option for a fifth year.
