Lilja blocked for Manning from 2004 to 2009 with the Indianapolis Colts, so it's a good bet that even without the injuries, the quarterback would have been consulted.
Manning also added that Lilja was considering a return to the league prior to signing with the Broncos last week, so the veteran offensive lineman didn't need a ton of coaxing to join the four-time NFL MVP.
"So this was not something where he just decided he wanted to play," Manning said. "Playing again has been on his radar. I had a good talk with him. So that's how that came about."
