"He's an athlete," Fassel said. "I like what I saw in him. He has a motor. He might be a defensive lineman and also help us on special teams."
Frisch said he believes he can contribute against the Eagles on Monday Night Football.
"I'm lucky I came in on the bye week because I have some time to learn the terms they use here," Frisch said. "I've pass-rushed against (Philadelphia tackle) Tre Thomas quite a few times. I think I can be effective and help this team."
Fassel on the state of the team: "I'm not happy being 3-3. It's basically because we've been inconsistent in our performance. I know I'm being a little unrealistic, because everybody is that way to a degree. I told the team this morning that the most important thing to me is that this is a race in this league to see who can continue to improve and be consistent."
