FRISCO, Texas -- The Cowboys have signed Mark Sanchez as a backup quarterback and are keeping their options open with the injured Tony Romo.Dallas added Sanchez to the 53-man roster on a one-year contract Sunday while waiving Jameill Showers with the likely intention of adding the second-year player to the practice squad if another team doesnt claim him.Rookie Dak Prescott is set to start the opener Sept. 11 against the New York Giants, but the key to the quarterback puzzle remains Romo, who broke a bone in his back in a preseason game against Seattle.The Cowboys can put him on the injured reserve-return list, which would free up a roster while sidelining the 36-year-old for the first seven games.Thats an ominous number for Dallas because its how many games Romo missed after he broke his left collarbone the first time last season. The Cowboys lost all seven games before Romo broke the same collarbone and missed four more. Dallas finished last in the NFC East at 4-12 a year after winning the division.If Dallas decides to keep Romo on the active roster, he can return whenever hes ready. The Cowboys havent said how long he will be out following his fourth back injury in less than four years.Prescott had a strong start to the preseason after Kellen Moore broke his right ankle in practice at training camp, and the Cowboys ultimately decided to give their fourth-round pick the backup job.After holding off on adding a veteran following Moores injury, the Cowboys knew they would have to add one once Romo got hurt.Showers, who spent most of last season on the practice squad, was spotty in his best shot at an audition while playing the entire preseason finale against Houston. But he has versatility because of his work on special teams in practice last season, making him an attractive option for another year in a similar role.Tight end Rico Gathers, the former Baylor basketball player trying to make the transition to football, was among seven players who cleared waivers and were added the practice squad.Defensive end Ryan Russell and receiver Vince Mayle, both second-year players, made the practice squad. So did four rookies: center Jake Brendel, receiver Andy Jones, linebacker Deon King and tight end Austin Traylor.---AP NFL website: www.pro32.ap.org and www.twitter.com/AP-NFL Wholesale Custom Angels Shirts . -- Adam Snyder returned to the San Francisco 49ers this season because the offensive lineman thought it was his best opportunity to win a championship.

Danny Willett has revealed his parents and wife were targeted by rowdy Ryder Cup fans.The Masters champion was picked out for abuse at Hazeltine after his brother Pete wrote a scathing article criticising the behaviour of American crowds.His sibling dubbed the home support a braying mob of imbeciles ahead of the competition but Willett, 29, was quick to offer an apology.However, after being subjected to boos and heckles throughout his three days on course, Willett later tweeted to say his brother was, in fact, correct after claiming some fans dont know when to call it a day.Now he says his first taste of Ryder Cup action was spoiled after abuse was even aimed at his family.Willett, who lost all three of his matches, told Sky Sports News: Youve got 150-200,000 fans there that love watching golf. Unfortunately youve got the odd one or two that dont actually go there to watch the golf, which is a shame.But I dont think thats ever going to stop. We got a taste of it last week, being in America with the fans and how they push on to help their team win.I think people realise what was said was reflecting on a massively tiny prooportion of people that went there.dddddddddddd. Thats just how it is, unfortunately.When youre walking round a golf event week to week, everyones fantastic. You pitch up and play a normal golf event anywhere in the world and the fans are great.I dont think you should be walking around playing golf while people are saying things to your parents and saying things to your wife. I dont think thats our sport, thats not what we play for, thats not what we do.Unfortunately that happened and unfortunately it put a little bit of a downer on what was supposed to be my first really good experience of the Ryder Cup.Willett raised smiles at the post-tournament press conference when he summed up his debut experience in blunt terms. S---, he said. Being honest. Sorry, would you like me to elaborate? Really s---.But now he admits he could have chosen his words more carefully, saying: Its difficult when you have a press conference straight afterwards, the emotions running high. It has sunk in a bit more now. ' ' '
