Earlier this week, several Penn State players talked about a hard-hitting drill called "The Lions' Den' that the team has been doing in practice this spring.
It is new coach James Franklin's name for the traditional Oklahoma drill, where a small number of players are put into a small space and basically bash away at one another.
We were able to check it out during Saturday's practice. And that means you can now check it out, too.
Watch the video above to step inside "The Lions' Den."
