What is this movie?

I saw it advertised on TV a couple of weeks ago, from what I remember it involved a boxer (i think) that was sent to prison and in prison he gets into a big fight or encounter with this russian guy who claims to be the #1 fighter or something. it looked cool and I can't seem to remember the name of it. it came out just a week or 2 ago.

That sounds like the sequel to Undisputed, Undisputed II: Last Man Standing.

Really? I'll look into that, thanks.
