Boxrec has this fight listed as being on 9/29 same day as Taylor/Pavlik and Maskaev/Peter, who is televising this fight, is it on an undercard?

Showtime is televising it during their free preview weekend. Maskaev-Peter is the following week.

You mean Sept. 29th and October 6th arent the same day?

I'm very excited for September through the end of the year, especially the span starting with Marquez and culminating with Floyd/Ricky. This will be one of the best overall months Showtime has ever had with Vitali/McCline, Dawson/Diaconau, Maskaev/Peter. They also have a nice ShoBox or two coming up.
