America's biggest weekly spectacle is also a dangerous one, and today's Seahawks vs. Cowboys game provided a scary reminder.

Ricardo Lockette took a violent and legal hit from Jeff Heath that left him motionless on the middle of the field. Lockette was carted off after lying for several minutes.

We'll keep you updated on his status, but Lockette gave an optimistic thumbs up as he was carted off the field. There's also movement in all his extremities, according to ESPN's Ed Werder.
