Brian Kenny, a host of Sportscenter, own ESPN radio show and boxing’s Friday Night Fights, is leaving the network after 13 years.

USA Today’s Mike McCarthy reported that Kenny’s run at ESPN will end in early September, and he’s likely to land at MLB Network (although it isn’t saying anything yet, presumably because his contract is not yet up). Kenny would be the 2nd ESPN staffer to leave for the MLB Network recently (Peter Gammons made the move in 2009 after 20 years at ESPN).

I suppose the biggest questions are who will replace Kenny as Jay Harris’s wingman on the 6 pm Sportscenter (Cindy Brunson? John Anderson? John Buccigross? newbie Lindsay Czarniak?), and who will take over his 5-days-a-week radio show (8-10). Also, who will be ESPN’s boxing voice? Who will spar on Sportscenter with Money Mayweather? This has to be one of the top five Sportscenter interviews in the last 20 years. It’s riveting and Kenny more than holds his own as Mayweather attempts to dance around every pertinent Manny Pacquiao question.
