This Saturday night's HBO Boxing After Dark will be headlined by a pair of electric 154-pounders in a must-see matchup that promises action, whether it lasts 40 seconds, four rounds, or somehow goes the long haul. Here's the official but entirely unimaginative HBO poster:

It's the Boxing After Dark template + the Pacquiao vs Marquez 24/7 plug! Yaaay!

The co-feature, which hasn't been hyped a lot but is also a good fight, will see 160-pound prospect Peter "Kid Chocolate" Quillin (25-0, 19 KO) take on Craig McEwan (19-1, 10 KO). McEwan is coming off of his March 12 loss to Andy Lee, but it was a hell of a fight and the 29-year-old Scot should be a good test for Quillin, who at 28 is trying to fast-track his way out of prospect status and into legit contention. Quillin has the talent, but to date he's yet to face someone who was any real danger to defeat him. McEwan may or may not be that guy, but I expect this to be another good fight.

For those wondering, and we will have a schedule up this week (on Wednesday), we will have round-by-round coverage of both shows on Saturday night. I'll be handling the Showtime double-header, which starts at 9 p.m. EDT, and Andrew Fruman will be here for the HBO show at 10:15. It should pretty easily line up so that the main event of the HBO show is unopposed, and we might get lucky and not have the SHO broadcast cut into the HBO opener, too.
