Long-reigning titlists Chris John and Omar Narvaez will make their returns to the ring in September, putting their featherweight and super flyweight titles on the line once again.

John, 32, will fight on September 29 in Singapore, according to Sampson Lewkowicz. No opponent has been announced, but it doesn't sound as if John (47-0-2, 22 KO) will be doing much more than the usual, i.e. facing a mediocre, mid-tier opponent and racking up another likely successful title defense. It will be the 17th defense of the WBA featherweight title that John won back in 2003. In his last fight, the Indonesian star easily defeated Shoji Kimura in Singapore on May 5.

Narvaez, 37, will again defend his WBO super flyweight belt on September 22 in Argentina. Like John, he has no opponent named yet, but also like John, it's not expected to much more than normal. Both are quality fighters, but have undeniable reputations for weak title defenses.

Narvaez (36-1-2, 19 KO) sacrificed his "0" last year for good money at bantamweight against Nonito Donaire, a fight that left nobody happy in the end. He returned to the ring in April of this year, beating Jose Cabrera in Argentina in a typical title defense.

The Argentine standout won the WBO flyweight title in 2002, in just his 12th pro fight, and made 15 successful title defenses before moving up to super flyweight in 2010, when he beat Everth Briceno for the vacant belt. He's made four defenses of that title to date.
