The following comes from an article on Fiveouncesofpain.com:
That airing back on May 31, 2008 scored 4.3 million viewers and a 1.9/6 among 18-49 year olds and since the Kimbo Slice bout for that airing aired past primetime (11p) the most viewed portion wasn’t included. But lacking any Kimbo anticipation, last night’s fights pulled a mere 2.62 million and a 1.0/3 from 9pm-11pm.
More info should come in over the next few days. It should be interesting to see how the final ratings come in and what it could be for EXC on CBS.
