The NFL has released some intimate audio and video from the sidelines of Super Bowl XLVII, and one of the most interesting exchanges was filmed on the Ravens sideline before the final play of Baltimore’s 34-31 win. As Sam Koch prepared to boot a free kick to San Francisco 49ers return Ted Ginn Jr., quarterback Joe Flacco encouraged his teammates to run onto the field and tackle Ginn if it looked like he was going to score. This, of course, is illegal and could have resulted in an automatic touchdown, but Flacco didn’t know the rule. Here is the transcription of the audio courtesy of Yahoo Sports’s excellent NFL blog Shutdown Corner: "If he starts to break it, go tackle him," Flacco said to Dennis Pitta. "Really?" the tight end responded. "I don't know ... I mean ... what else can they ... they might be able to give them a touchdown on that? I don't know," Flacco told Pitta. Flacco then approached the offensive linemen with his new tactic. "Hey! If he breaks this ... if he busts it for some reason? Tackle him! Go tackle him," Flacco said to guard Marshal Yanda and center Matt Birk. "I don't know what the rule is on that, but..." "Why don't you?" Yanda asked. "I'm going to!" Flacco said.

Whatever the rule may be, it couldn't result in a touchdown. They would only be able to tie it with a field goal or take a shot with 0 seconds left from wherever the penalty may put them.
NFL rulebook I think Flacco was just freaking around. He's got a dry sense of humor and he is one of the more comical guys on that team from what I understand.
You know, I'd probably say the same in hopes that one of my teammates would do it...lol. But of course I'd be 75% joking...
