The Indianapolis Colts confirmed Tuesday that they will select Stanford quarterback Andrew Luck with the top overall choice in the NFL draft Thursday night. That leaves Baylor quarterback Robert Griffin III to be taken by the Washington Redskins with the second pick.

Colts General Manager Ryan Grigson made the announcement to reporters at the team’s minicamp.

“In fairness to Andrew Luck and fairness to the whole process… I thought it was the right thing to do to announce we’re going to take him,” Grigson said, according to the Indianapolis Star. “I didn’t see the point in prolonging what the world already knows. It’s about Andrew. We wanted to do the right thing by him.”

The Colts informed Luck last week that he would be the top pick, according to a person familiar with the situation.

The Redskins have the second overall choice, thanks to last month’s trade with the St. Louis Rams, and have targeted Griffin, the Heisman Trophy winner, all along.

The Redskins declined to comment Tuesday through a spokesman. They are scheduled to conduct a pre-draft news conference Wednesday. Redskins officials previously had said they would take either Griffin or Luck, whichever quarterback the Colts didn’t select.
