Tim Howard is an American hero of sorts after some amazing performances with the U.S. national team, but even heroes can go into full tilt. Howard and the Colorado Rapids were handily beaten 3-1 by Sporting Kansas City, with the Rapids struggling early on in the MLS season. They've won just one game and haven't been able to scratch the victory column on the road. Tempers seemed to flare between Howard and SKC's Dom Dwyer, or at least from Howard. The goalkeeper was scored on by Dwyer in the 85th minute, sealing the Rapids' fate, and didn't appear to be taking the loss in stride.Howard approached Dwyer after the game in what typically is a handshake between competitors. The two embrace, but as Howard walks away something triggers a nasty spat between the two.Here's some video footage of the outburst, courtesy of FOX Soccer:

It appears Howard says something as he's walking away that Dwyer takes offense to. Dom responds, which only sets Howard off more. Tim walks back and points his finger directly into Dwyer face and is furious over something.

We may never know what that something is, though. Dwyer was asked about the argument shortly after it occurred and had this to say when questioned about what happened. 

"[I'm] not really sure to be honest with you. It was a fantastic team performance, a lot of respect for them as players. It's a very good battle, I'm not going to talk about players on here," Dwyer said. 

It's an interesting situation, particularly with expectations swirling that Dwyer may join the U.S. national team after becoming a citizen. The England-born striker may have some ironing out to do with the world class keeper. 

Losing never comes easy at the professional level, and Howard's accomplishments surely make this rough patch with the Rapids even more painful. Naturally, star players have a certain level of pride, and losses tarnish it. 

Assuming whatever happened here isn't really fair to either competitor, though. Dwyer may have done absolutely nothing wrong, and Howard may be in the right to be triggered by something Dom may have done. Simply put, we have no idea what went on or why. 

But Howard was visibly furious, and after another tough loss and being scored on three times, anything may have pushed him over the line between simmering anger and outright fury. 

We'll find out if they're teammates come June when the national team roster is announced.
