    Romance isn't dead in the FA Cup

    Barnet's David Tutonda leads the celebrations following his side's 1-0 victory over Sheffield United.
    The "romance of the cup" is a well-worn FA Cup cliche, but fans of Barnet, Oldham Athletic and Newport County are feeling the love as the three lower-league sides overcame fancied opposition -- Sheffield United, Fulham and Leicester respectively -- to advance to the fourth round of the football's oldest cup competition.
      Barnet -- currently languishing in 15th place in the National League, the fifth tier of English football -- provided arguably the shock of the day by beating Championship side United 1-0, courtesy of a Shaq Coulthirst penalty early in the first half.
      For Oldham's caretaker manager, Pete Wild, it was a day to savor as his unfancied side rose to the occasion to put away Premier League Fulham 2-1, with the London side currently 59 places above the Latics in the league structure.
      Oldham manager Pete Wild celebrates with player Sam Surridge following Athletic's FA Cup thrid round victory.
      "It means a lot to me and my family. We're all Oldham people," he said after securing the win. "We're from a small town overshadowed by big neighbors and I'm so proud to give something back."
      Newport manager Michael Flynn was equally ecstatic with his side's 2-1 win over the Foxes. "It's almost 'Roy of the Rovers' stuff, I can't believe it," he said, referencing the classic football comic. "It's the first time I've beaten a Premier League club as a manager so it's one I'll never forget. I'll have a few drinks with the wife tonight."
      Manchester United's Norwegian caretaker manager Ole Gunnar Solskjaer gestures to the crowd at the end of his team's match against Reading at Old Trafford.
      Elsewhere, Manchester United carried its newfound confidence under caretaker manager Ole Gunnar Solskjaer with a 2-0 win over Reading, while neighbors City equaled Spurs' 7-0 thumping of Tranmere, strolling to its own 7-0 win over Rotherham. Arsenal and Chelsea also progressed, 3-0 against Blackpool and 2-0 over Nottingham Forest, respectively.

      Good weekend for the 'Cs': Cowboys, Colts, Chargers all progress

      Dallas Cowboys' Allen Hurns suffers a leg injury when tackled by Seattle's Bradley McDougald.
      As the NFL season moves into the do-or-die stage in the run-up to the Super Bowl in Atlanta in February, Dallas, Indianapolis and Los Angeles laid down early markers. The Cowboys' Dak Prescott inspired his teammates, edging the Seahawks, 24-22, on Saturday at AT&T Stadium.
      Prescott showed he can handle the spotlight with a big fourth quarter play for a 16-yard gain, before scoring the game-winning touchdown from the one-yard line. It was a stellar start to the postseason for the 25-year-old, who also completed 22 of 33 passes for 226 yards.
