Manning injured his right ankle on the play, and the Broncos sent the play into the league as a questionable hit because there was contact below the knee. Check out the play here.
However, the league said that Liuget's hit was a legal play. Liguet was not flagged for the play and will not be fined by the NFL. On the play, Liuget made initial contact above Manning's knees to his thigh area before wrapping below the knees and taking him down.
"I didn't really pay too much attention to it," Liuget said. "But the NFL said it was a legal hit, so I guess it is a good hit then."
Liuget was asked if he was concerned that some would think he intentionally tried to injure Manning.
"That's Peyton Manning," he said. "I'm never in the game to hurt anyone or go after anyone. And my whole thing was to just try and make a play.
"I know my real true intentions. And the league knows that it wasn't a dirty hit or anything. So I'm totally fine with what I did on the play."
San Diego coach Mike McCoy said that Dunlap suffered a neck strain and not his third concussion, as the team previously reported during the Denver game last week.
McCoy does not know how long Dunlap will be out.
McCoy also got his first look at outside linebacker Adrian Robinson, who replaces Larry English on the 53-man active roster. English was placed on the injured reserve list with a season-ending pectoral injury.
"He was a player that we worked out earlier this season that we were looking at if we needed to add an outside linebacker," McCoy said about Robinson. "He's played in a scheme similar to ours obviously in the past in Pittsburgh a little bit. And then he was in Denver this past offseason, so it's a good fit for what we're looking for."
