There’s no love lost when Indiana and Duke square off on the basketball court.

These two powerhouses have had some epic battles over the years, so when a questionable incident happened during Wednesday night’s matchup, it’s hard to write it off for occurring on accident.

With Duke leading 51-42 heading into the half, Indiana’s Max Bielfeldt appeared to bump into Duke coach Mike Krzyzewski on his way to the locker room. And Coach K was pretty upset about it.

Coach K had some words with the refs, as well as Indiana coach Tom Crean afterward.

Intentional or not? It looked to be purposeful to me, but it’s hard to know for sure.
