INDIANAPOLIS -- In the latest deflategate twist, Colts general manager Ryan Grigson admitted during a news conference Thursday that his team passed along its suspicions about the Patriots' under-inflated footballs before the AFC championship game.

"Earlier that week, prior to the AFC Championship game, we notified the league about our concerns," Grigson said. "We went into the game, we had some issues, but you know, we're going to do what we can -- and that's to participate with the league and the investigation and wait until the Wells report comes out. We really have no other recourse but to wait until the investigation comes out."

Pressed for more, Grigson said, "I'm not going to get into specifics...I just did my job and here we are. And hopefully everything will come out and we'll have a clear look at the situation."

Grigson would not identify the reason why the Colts were suspicious prior to the game.

"Just like any general manager who wants their team to win on a level playing field, we took the proper steps to try to ensure that," Grigson said. "It's up to the league to make sure that that happens. Again, if rules were broken, we'll see. If not, that's what the investigation is for."
