Grigson spoke Thursday at the NFL combine but did not say what prompted the team to talk to the NFL about the issue.
“Earlier in that week, prior to the AFC Championship Game, we told the league about our concerns," Grigson said. "We went into the game, we had some issues. We're going to do what we can which is participate with the league and the investigation and wait until the Wells Report comes out. There's no other recourse other than to wait until that investigation comes out."
The Most Talked-About Footballs in NFL History
Grigson called any thought about the Colts deflating the Patriots footballs on purpose, “ludicrous."
The ongoing investigation into the allegations against New England is being led by Ted Wells.
"Again, if rules were broken, we'll see," Grigson said. "If not, that's what the investigation is for."
