West Coast boxer Chester Slider spent his time yo-yoing between WW and MW. His name might make him a candidate. "And after that rounds, Slider's face is hamburger." or "The holes in Slider's game have been exposed."
The issue of the Referee from 1846 previewing his bout with Major Jones describes him as having boxing skills and an ability to work inside.
