A few notes from around the boxing world:

• The NBC-televised card on Saturday night (8:30 p.m. ET) from the Barclays Center in Brooklyn, New York, will include the Danny Garcia-Lamont Peterson welterweight bout and Andy Lee’s middleweight title defense against former titleholder Peter Quillin, but two other bouts are also on tap for possible television coverage: light heavyweight Marcus Browne (13-0, 10 KOs), a 2012 U.S. Olympian, against Aaron Pryor Jr. (19-7-1, 12 KOs) and welterweight Errol Spence Jr. (15-0, 12 KOs), also a 2012 U.S. Olympian, against Samuel Vargas (20-1-1, 10 KOs). One of them could be televised on NBC if there are early knockouts in the other bouts and at least one of them will air live on NBC Sports Net (11 p.m. ET) following the conclusion of Garcia-Peterson on NBC.

• Among the fighters Golden Boy Promotions announced will appear on the untelevised undercard of the Canelo Alvarez-James Kirkland fight on May 9 (HBO) at Minute Maid Park in Houston, where a crowd of some 40,000 is anticipated, are featherweight prospect Joseph Diaz (15-0, 10 KOs), 7-foot Chinese heavyweight prospect Taishan Dong (3-0, 2 KOs), former welterweight titlist Joshua Clottey (38-4, 22 KOs) and welterweight James Leija Jr. -- son of the former titleholder – who will be making his pro debut.

• Main Events promoter Kathy Duva announced Wednesday that she has signed 30-year-old Latvian cruiserweight Mairis Briedis (14-0, 11 KOs) to a co-promotional agreement. Briedis is promoted overseas by J.C. Courreges' Biggers Better Boxing but the co-promotion deal will cover Briedis' fights in the United States and Canada. "I'm very happy to be joining Main Events and I truly believe that this will be a turning point in my career,” he said. “I appreciate that Ms. Kathy Duva and Main Events have believed in me and are ready to give me a platform to reach my highest goals of becoming the world champion. I'm looking forward to introducing myself to the American boxing world and show how tough Latvians can be in the boxing ring.”
