NFL Redzone

I have the Xfinity Sports Package.  I used to get NFL Redzone in that package.  I tried using it for first time this year and it says it is no in my package.  I checked all the other sports channels in the package, including NFLN, and it is still there.  I called Xfinity customer service and was told that the NFL has made that a separate premium channel (another 10 bucks a month) on top of the sports package.  I would like confirmation that is the case, as I see nothing online that verifies that.  My friend has the same package and he still gets Redzone.  Again, I get all the other sports channels so it is something specific to Redzone.  And up to this year Redzone came with the same package.
