Former two-weight champion Cory Spinks appears to be heading for retirement after a lop-sided defeat to Carlos Molina on Friday.
The awkward southpaw showed precious little against the fringe contender, being docked a point as early a round four for excessive holding.
He was dropped by a left hook in the 11th round and received a standing count in the finale when it was ruled the ropes stopped him from going down again.
Scores of 120-105 and 119-106 twice reflected Molina's superiority and how far Spinks has regressed.
The son of former heavyweight king Leon, Spinks stunned Ricardo Mayorga to become undisputed welterweight champion in 2003 despite being a heavy underdog.
He defended the belts successfully against Zab Judah but the New Yorker gained his revenge in 2005.
Spinks stepped up to light-middleweight, where he twice won the IBF belt, while he also fought middleweight champion Jermain Taylor where he lost on a split decision.
If he does decide to retire, Spinks hangs up the gloves with a 39-8 ledger.
On the same bill in Chicago, another former champion Jose Luis Castillo also looked a shadow of his former self as he lost to Antwone Smith.
Fighting at light-middleweight for the first time, the 39-year-old was repeatedly caught on the counter as he dropped to 64-12-1 on scores of 100-90, 99-91 and 98-92.
The former lightweight champion was considered past his best when he was stopped in four rounds by Ricky Hatton in 2007, and never again fought for a world title.
At his best he twice went in with Floyd Mayweather and was considered unfortunate by many not to get the verdict in their 2002 rematch.
