"Challenge Court" logo font from back in the 90's

I've heard you guys are the best for this kinda stuff, been looking on databases for hours to no avail so this is kinda my last resort...

Anyhow, I'm trying to identify the font that was used in Nike's "Challenge Court" line of clothing logo back in the 90's (it was Andre Agassi's stuff).

Here's a reference picture from one of my tees:


The font is approximately from 1991~1992 and looks an awful lot like the "Silhouette LP" one, however the "R" and "N" don't quite match seeing as the former's gotten a sort of upper-left serif and the latter is completely different.


woah it really is Modula Sans bold, thanks a bunch Jan!!!
