Some short jabs ...

• The most entertaining fight of Saturday night's show headlined by Bernard Hopkins' light heavyweight title defense against Karo Murat could be the middleweight showdown right before it. WBO champion Peter Quillin (29-0) defends his title against Gabriel Rosado (21-6) in a fight between two men who don't back up much. Rosado, a 154-pound contender, moved up earlier this year to face Gennady Golovkin, only to get stopped in the seventh round. Quillin has shown steady improvement since turning pro in 2005 and isn't afraid to slug it out. If Rosado has his way, that's exactly what will happen.

• Golden Boy Promotions CEO Richard Schaefer told SI.com that he has advised heavyweight prospect Seth Mitchell to retire. Mitchell (26-2-1) is coming off a first-round knockout loss to Chris Arreola, his second knockout defeat in his last three fights. In both fights, Mitchell showcased a weak chin.

"I spoke with his trainer and my recommendation was that he moves on and does something else," Schaefer said. "I don't know if that's what he is going to do. It sounded to me like his intention was to continue boxing. Freddie Roach came up with the phrase 'You can't teach a chin.' Seth is one of my favorite guys. He will be welcome at any Golden Boy event. I will be there for him. I just think that he might get three or four wins against subpar opponents. I just think you have to take a step back and see if that is really what he wants to do or is there an opportunity to do something else."

• Schaefer also defused the possibility of Hopkins as a future opponent for Floyd Maywether Jr. In the aftermath of Mayweather's win over Canelo Alvarez, Hopkins suggested he could make 160-pounds if Mayweather was willing to move up to face him. Schaefer, though, said that fight was unlikely.

"I really haven't had any conversations with Floyd about fighting at middleweight," Schaefer said. "At 154, it's a big weight. He's a 147-pounder. I doubt it. I just don't see Floyd fighting at middleweight."

• If you have not seen HBO's Legendary Nights documentary on Arturo Gatti and Micky Ward, make sure you do. It's a gripping tale about two gladiators who became friends, about three fights that forged a friendship that will live on even in death.

• 2008 U.S. Olympian Jose Ramirez is developing into a popular young fighter. On Nov. 9, Ramirez, a Top Rank-promoted prospect, will fight Erick Hernandez in Lemoore, Calif., 45 minutes outside of Ramirez's hometown of Avenal, Calif. Ramirez has sold more than 3,000 tickets and 32 VIP tables while drawing in name sponsors Wonderful Pistachio, Dodge, Pepsi and Harris Ranch Beef. Developing a following in one area is often overlooked in the casino-happy boxing landscape. If Ramirez (6-0) continues to rise, he could quickly become a marketable star.

• The good news for Main Events: The success of the Fight Night series it promotes on NBC and NBCSN has helped create such premium network stars as Sergey Kovalev, Curtis Stevens and Gabriel Rosado. The bad news? The rise of those stars--and the decision by Bryant Jennings to sign with Gary Shaw--has left the promotional company searching for a main event for the December NBCSN show.

• It's a shame that Shane Mosley's fight with Anthony Mundine fell apart. Not for the fans; a Mosley-Mundine clash is hardly must-see TV. But for Mosley, who will have a tough time finding $1 million paydays anywhere else.

• Promoter Artie Pelullo's pledge of allegiance to HBO following Ruslan Provodnikov's compelling knockout win over Mike Alvarado took possible fights between Provodnikov and either Danny Garcia or Lucas Matthysse--Golden Boy-promoted fighters who fight exclusively on Showtime--off the table. It's too bad. The relentless Provodnikov against either would have been a terrific fight.
