Though none of the undercard fights are airing tonight on HBO, and aren't streaming anywhere online (which is a shame, Golden Boy has that capability and plenty of sites on which to stream the fights), we'll keep you updated with live results from the undercard as they come in. The main event tonight between Amir Khan and Zab Judah airs at 10 p.m. EDT on HBO.

For round-by-round updates from the first five bouts, check out The RING Magazine on Twitter. Bad Left Hook's thoughts on the rest of the card in the comments.

• Jamie Kavanagh UD-6 Marcos Herrera: Kavanagh (8-0, 3 KO) is a Dublin-born lightweight now based in Los Angeles, and keeps his undefeated record on scores of 60-54, 59-54, and 60-53 over Herrera (6-6-1, 2 KO). You may recall seeing Herrera in April on Friday Night Fights, when he was game but easily outclassed by another Golden Boy prospect, Hylon Williams Jr, at the Cosmopolitan in Vegas.
• Josiah Judah MD-6 Rafael Jastrzebski: Judah (10-1-1, 2 KO) is a super middleweight and sort of the lost Judah brother, not near Daniel's level and not even in the same universe as Zab. This was his first fight in three years, and he was reportedly outworked by Jastrzebski (4-7-1, 1 KO) in the first three rounds, but won on scores of 59-55, 58-56 and 57-57.
• Ronny Rios TKO-1 Noe Lopez Jr: Rios improves to 15-0 (7 KO) but takes nothing better than a sideways step with this win. The 21-year-old super featherweight prospect has had some inconsistencies thus far in his pro career, but has an exciting style and some real promise, too. Lopez is now 7-9 (4 KO), and has been a favorite of Golden Boy and other promoters as a prospect tester the last few years. The stoppage came on a body shot at just 1:12.
  
• James Kirkland TKO-2 Alexis Hloros: The Michigan club patsy at least came to fight, says The RING, and threw all he had at Kirkland, who responded by knocking Hloros down three times and bashing his way to another victory. Kirkland is now 29-1 (26 KO), while Hloros slips to 15-4-2 (11 KO). Hloros was down twice in the first, then again early in the second, but went out throwing punches.
• Bryant Jennings UD-6 Theron Johnson: Johnson (9-0, 4 KO) is a heavyweight prospect from Philadelphia, 26 years old and 6'2" with weights in the low 220s. Scores here were 60-53, 60-53, and 59-54. Johnson (5-6, 1 KO) was down in the 4th round.
• Gary Russell Jr UD-8 Eric Estrada: Estrada has a career as a prospect checker ahead of him if this performance is any indication. Russell (17-0, 10 KO) easily dominated the fight with pure skills and busted Estrada up over the distance, but Estrada (9-2, 3 KO) was tougher than all hell and only went down once, and that was just a glove touching the canvas in the seventh round. HBO will air highlights of this one tonight.
• Peter Quillin TKO-5 Jason LeHoullier: Terrible mismatch, and an opponent who came in on a week and a half notice when Tarvis Simms shockingly (!) dropped out (no way!) of the fight. Quillin improves to 25-0 (19 KO) by handing undersized, underprepared LeHoullier (21-6-1, 8 KO) his sixth straight loss. The corner stopped it out of mercy, and it was a good decision. LeHoullier was being toyed with and beaten up.
