Khan vs Alexander: Live streaming results and round by round coverage

Bad Left Hook will have full live coverage of tonight's lengthy and hopefully entertaining Showtime Championship Boxing card, headlined by Amir Khan and Devon Alexander meeting in a pivotal welterweight showdown, and Keith Thurman in the co-feature against Leonard Bundu.

All four of those 147-pound fighters will be looking to break through, and Khan, Alexander, and Thurman in particular are hoping to impress and potentially land a spring 2015 fight with Floyd Mayweather.
