@Alt What I've heard is that the magazine wanted to end several long-running mangas and replace them with new comics by younger authors(that were paid less). Keijo! just had the misfortune of being one of the comics targetted.
Not popular enough and apparently the anime didn't help its popularity, and as it was already in decline that was the final nail as adaptations almost always result in more readers/volume sales...
Every time I read a new Keijo!!!!!!!! chapter I just can't help but laugh hysterically at those no context shit.
"I lost to my past asses!?" LMFAOOOOOOOOOO
