Cam Newton is often described as one of the more laid back quarterbacks plying his trade in the NFL but his cool-demeanour slipped at Carolina Panthers training camp today.
As we have already seen in Houston, Dallas and Indianapolis tempers can flair at this time of year as players prepare for the 2015 NFL season, and the Panthers were the latest to fall victim to in-fighting today.
It was Newton and cornerback Josh Norman who were at the center of the ruckus on Monday morning, the latter's interception sparking a scuffle that required the help of several players to break up.

According to the Charlotte Observer's Panthers beat writer, Joe Person, the tension between Newton and his defensive teammate has been building all week - Norman's celebrations on an interception enough for Cam Newton to throw down.
Unfortuntely there isn't any footage of the fight but the Observer has a series of photos showing the two coming together on the field as helmets go flying. The fact Cam Newton is seen with a huge beaming smile as he goes at the CB making the whole thing fairly surreal.
The aftermath of the scuffle was caught on camera and you can clearly hear the Carolina quarterback tell his rival, "hit me like that again, you'll know something" as things settle down.
Fighting between team mates if far from a new phenomenon unique to 2015 training camps but, as Carolina Panthers head coach Don Riviera noted after practice, it usually takes a little longer before punches are thrown.
Players and coaches usually don't mind seeing a little bit of frustration released like this so long as it doesn't become a regular occurrence.
Anyway, with the Panthers hoping for much bigger and better things in 2015, their fans might be grateful to see just how seriously both offense and defense are taking things right now.
