The busy schedule of the star's lawyer is to blame for the hold-up...

JAY-Z‘s forthcoming trial on assault charges has been delayed once more.

As previously reported on NME.COM, the rap star faces 15 years in prison if found guilty of stabbing Lance ‘Un’ Rivera during an incident at New York’s Kit Kat Club in December 1999.

Jay-Z‘s defence teams claim he was nowhere near the vicinity of the fight and have video footage proving he was not at all involved.

According to MTV news today (July 19), the trial, which was originally due to start in February this year and was then postponed until mid-July, will now not start until at least September 5 because of the busy schedule of Murray Richman, a lawyer acting on behalf of Jay-Z.

Richman is working on another case, unrelated to Jay-Z.
