According to Ring Magazine, the slip comes after  the 28-year-old Joshua suffered his first defeat as a professional via a seventh-round knock out by Andy Ruiz Jnr. at  Madison Square Garden.

The win also saw Ruiz Jnr. crowned the unified heavyweight champion, the first Mexican-American to achieve the feat. Joshua is now one place behind him.
