Don't spill the magic bean
Game:Titans 23, Bills 17
Things got a bit nutty when ...C.J. Spiller runs off left tackle and breaks free on a promising run. However, Michael Griffin pokes the ball loose at the 5-yard line, it bounces into the end zone, where Spiller apparently recovers for a touchdown. The referees rule that Spiller didn't recover the ball until it was behind the back of the end zone. The Bills challenged the ruling, won said challenge and were rewarded with a touchdown. It was all a somewhat confusing sequence of events, so it's best to check out the play for yourself.
Dubious beginning to Orton era
Game:Chiefs 10, Bears 3
The situation: Facing a second-and-10 situation from their own 43-yard line and the game tied at 0-0, the Chiefs begin the second quarter by replacing starter Tyler Palko at quarterback with the newly acquired Kyle Orton, who gets a shot at showing his former team what they might be missing.
Things got a bit nutty when ... The Chiefs opt for some razzle-dazzle with their new passer now on the field. Orton's pass after a flea flicker flutters incomplete. But Orton was hit on the play by Bears safety Major Wright as he released the ball. Orton hurt a finger on his throwing hand and would not return to the game.
Like father, like son
Things got a bit nutty when ... Fans of the Steelers are familiar with Brown's post-scoring dance moves, and it turns out so is his young son. CBS provides viewers with a split-screen shot of Brown Jr. and Brown each doing the now-famous touchdown jig.
Prayer answered
Game:Chiefs 10, Bears 3
Things got a bit nutty when ... Palko's long lob finds the end zone, where Bears linebacker Brian Urlacher attempts to knock the ball down, but instead it lands in the arms of Dexter McCluster for a Chiefs touchdown (in a play eerily reminiscent of the Jaguars' winner against the Texans in Week 10 of last season). The score stood as the only touchdown in the entire game as the Chiefs held on to prevail.
Icing your own kicker?
The situation: With the score tied 13-13, the Cowboys drive down the field in the final minute for what appears will set Dallas up nicely for a winning field goal.
Things got a bit nutty when ...Tony Romo hits Dez Bryant for a 15-yard gain to the Cardinals' 31-yard line. The Cowboys rush to the line of scrimmage to spike the ball and stop the clock with eight seconds left and set up kicker Dan Bailey for a 49-yard field goal attempt. Then, Cowboys coach Jason Garrett, right before Bailey booted what would have been the game-winner, called a timeout. Predictably, Bailey missed after the timeout, forcing overtime -- during which the Cowboys ultimately lost -- and giving Garrett a curious place in NFL lore.
