WZ has learned from sources that JBL will be added to the commentary team tonight at Night of Champions.
He's expected to make his entrance just after the pay-per-view goes live on the air.
We've also learned Jim Ross is expected to be added on commentary soon. We can't confirm if Ross will be on commentary tonight or held off until Monday Night. It seems both scenarios have been discussed.
I'll be giving live updates all night from Boston, so be sure keep checking WZ and follow me on Twitter.
