Former Broncos center Tom Nalen was inducted to Denver’s Ring of Fame on Friday when he admitted that he tried to blow out the knee of former Dallas Cowboy Igor Olshansky.

Olshansky was playing for the Chargers at the time. Nalen said Olshansky was playing dirty in the play before, putting his hands in Nalen's facemask.

"I wanted to blow his knee out on that play because of what happened the play before," Nalen told Pro Football Talk. But that, you know, is that dirty? I don’t know. It’s revenge, kind of, so."

Olshansky denied getting his hands in Nalen's facemask to ESPN Dallas.
