FRISCO, Texas -- Dallas rookie Ezekiel Elliott appears set for his preseason debut at Seattle after the running back taken fourth overall by the Cowboys missed most of training camp with a hamstring injury.Lance Dunbar was cleared medically this week following major knee surgery last year, and free agent Alfred Morris is shaping up as a solid insurance policy.The Dallas running game looks deep behind one of the NFLs best offensive lines, and thats without a mention of last years leading rusher, Darren McFadden. Hes been out nearly three months after breaking an elbow in a household accident.Once McFadden comes back, who knows how many carries there will be for him coming off his second career 1,000-yard season.I think a lot of people made a big deal about, we have so many running backs, coach Jason Garrett said. You can never have that many running backs. Weve found that out in the past.Like last year, when the Cowboys were fortunate to land a productive McFadden after letting 2014 NFL rushing champion DeMarco Murray go to NFC East rival Philadelphia in free agency. And Dallas didnt just hand the ball to the fourth overall pick from 2008, instead letting Murrays backup, Joseph Randle, have the lead job for six games.When Randle injured his back and McFadden grabbed the lead role, Dallas had a carousel of backups after releasing Randle. The Cowboys were lucky McFadden made it through relatively healthy for one of the few times in his career.Thats where Morris comes in. A two-time Pro Bowl pick in Washington, hes the likely No. 2 behind Elliott for the regular-season opener Sept. 11 at home against the New York Giants.The Cowboys, who drafted another running in the sixth round in Eastern Michigans Darius Jackson, essentially declared Elliott the starter by being ultra conservative with his hamstring in camp.I dont know my role, said Morris, who had 2,888 yards his first two seasons compared to 1,825 the past two. Whatever it is, whether its two plays, 100 plays, it really doesnt matter. I have to make the most of each one. And thats what Im doing.Elliott was the second-leading rusher in Ohio State history and scored four touchdowns for the Buckeyes in the championship game at the home of the Cowboys following the 2014 season. He was drafted higher than Hall of Famers Tony Dorsett and Emmitt Smith.Therefore, Morris doesnt see it as much of an issue that Elliott missed the better part of three weeks.I said in interviews, like, way a while ago, hes way ahead of where I was as a rookie, Morris said. I think hell have a good showing out there versus the Seahawks. Im sure looking forward to seeing him get out there. He hasnt had his preseason debut yet, so it should be a fun one for him.Garrett isnt ready to say Elliott will play on Thursday night, but did say the 21-year-old made it through practice Monday with no issues. Elliott wasnt available in the locker room when it was open to reporters.Its important for all players to practice and get their work in. Thats what we would like for everybody on our team regardless if theyre a first-year player or have played for 15 years, Garrett said. Hes done a really good job with his rehab getting himself back, staying engaged with the team.Dunbars been doing that since last October, when he tore two ligaments and the patellar tendon in his left knee while returning a kickoff at New Orleans. The loss of his versatility was an underrated reason the offense struggled while also missing quarterback Tony Romo (twice-broken collarbone) and receiver Dez Bryant (broken foot).While hes a ways from being cleared to play in a game, Dunbar is doing individual work at practice.We had to be very deliberate in saying, lets keep him out, Garrett said. Now we feel like its the right time to bring him back. Were excited to have him back. Hes an awfully good football player.Game notes DT Tyrone Crawford is being evaluated for a concussion after hitting his head during practice Sunday. It was the first indoor practice for the Cowboys at their new facility. ...

TOKYO -- Tokyo governor Yuriko Koike wants a new volleyball arena for the 2020 Olympics built in the citys waterfront Ariake district instead of using an existing facility in neighboring Yokohama.The proposal for a new venue comes despite a Tokyo government panel warning that the cost of the Olympics could exceed $30 billion -- four times the initial estimate -- unless drastic cuts are made.Koike had proposed moving volleyball, swimming and canoe sprint to existing venues outside the capital, but has now agreed that facilities for all three will be built in the city as originally planned.The final decision on the volleyball arena is expected to be made Dec. 21 during a teleconference of a four-party working group reviewing costs oof the 2020 Olympics.ddddddddddddSpeaking Friday, Koike said a plan is being considered to sell the operating rights of the arena to private firms after the end of the Olympics.Several other sports including gymnastics and BMX cycling will be staged in the same area.Tokyo organizers had previously backed the Ariake arena as it could be used for sports like figure skating, basketball and ice hockey after the games.Tokyo currently lacks a state-of-the-art sports arena large enough to stage international events.
