Brandon Carr dealt firsthand with tragedy last week, when former Kansas City Chiefs teammate Jovan Belcher took the life of Kasandra Perkins before committing suicide at the team's facilities.

After Carr left Perkins' funeral services on Saturday, he received even more bad news -- Jerry Brown passed away, and Josh Brent was arrested and charged with intoxicated manslaughter, stemming from Brown's death.

Needless to say, Carr was emotional following Dallas' come-from-behind win over the Cincinnati Bengals in Week 14.

"That interception was for a lot of heavy hearts, including mine," Carr said. "It's for everybody who's grieving right now."

Carr also conceded that he's taking an emotional beating over the past week.

"I'm like, man, how much can you take?" Carr said. "At the same time, God always says that he won't put more on you than you can bear."

Despite the heavy heart and emotional stress, Carr managed to play a gigantic role in Dallas' win over the Bengals. Carr intercepted an errant pass from Bengals quarterback Andy Dalton, and registered four tackles and a pass deflection.

Without Carr's contributions on Sunday, the Cowboys probably lose -- and see their playoff hopes disappear too. It's certainly a testament to Carr's work ethic and mental toughness that he was able to not only play, but play well on Sunday.
