I don't think it's such a big deal.  So a Triceratops got bit on the horn in 
a tiff with ol' rexy.  It's bound to happen sooner or later, considering 
these two probably faced off and threw their weight around against one 
another pretty regularly over the few million years they lived together.  I 
don't think it's as though T. rex was going out of its way to bite horns.  
Though if this horn-bitting behaviour does prove to be a regular thing, that 
might be a little surprising.
And for the one who asked about where these findings were published, there 
was an abstract on the issue in the last SVP abstract volume:

(It's John Happ's paper).
