HOUSTON -- Houston coach Gary Kubiak collapsed leaving the field at halftime of the Texans game Sunday night against Indianapolis and was taken by ambulance to a hospital. Kubiak hunched over and dropped to his knees at the 24 yard line and was immediately surrounded by medical personnel. He was lifted off the field on a stretcher and taken by cart to the ambulance. The Texans didnt say what was wrong with Kubiak, but did say he didnt have a heart attack. The team said the 52-year-old coach, a former NFL quarterback who calls the teams plays, was conscious and was with his family as he was taken to the hospital. "He had an episode; he was light-headed and dizzy," Houston general manager Rick Smith said in an interview on NBC. "He was evaluated by a number of specialists ... he is awake and coherent." Defensive co-ordinator Wade Phillips took over as coach. Up 21-3 when Kubiak collapsed, the Texans unraveled in the second half, falling 27-24 for their sixth straight loss after opening the season 2-0 with Super Bowl hopes. "We have to assess ... obviously, theres a lot of info," Smith said. "Hopefully, Gary will be back with us tomorrow." Kubiaks collapse came a day after Denver Broncos coach John Fox was hospitalized in North Carolina as he awaits aortic value replacement surgery. The 58-year-old Fox will have surgery in a few days and will miss several weeks while recuperating. Fox had been told earlier about his heart condition and was hoping to put off the operation until February. As part of his trip to North Carolina on a bye week, he met with his cardiologist in Raleigh and was told to seek medical attention immediately if he felt any discomfort. On Saturday, Fox became dizzy playing golf near his off-season home in Charlotte and was taken to a hospital, where tests revealed he couldnt wait any longer to have the surgery. In college, Minnesota coach Jerry Kill took a leave of absence last month so he could better manage and treat his epilepsy. He has had five seizures on game day in his two-plus seasons with the Golden Gophers. Kubiak has long been known as a top offensive coach, mentoring quarterbacks in Denver under Mike Shanahan and now Matt Schaub -- and Case Keenum -- in Houston. Kubiak has had no known public health problems. Kubiak was hired in 2006, along with general manager Rick Smith, after the Texans finished a franchise-worst 2-14. Smith spent 10 years with Kubiak while the coach was offensive co-ordinator of the Broncos. Smith was Denvers defensive assistant for four seasons before moving into the front office for his last six years with the Broncos. The pair has helped transform the Texans, which began play in 2002, from league laughingstock to contender. The team went 6-10 in their first year and 8-8 in each of the next two seasons. Expectations were high in 2010 after Houston finished at 9-7 for its first winning record in 2009. But the Texans instead fell to 6-10, which led to many fans calling for Kubiaks firing. His original contract was due to expire after the 2010 season, but owner Bob McNair has stepped up to keep Kubiak and defended him several times amid the bumps. Among recent departures were assistant head coach Alex Gibbs (for Seattle) and offensive co-ordinator Kyle Shanahan went to join his father, Mike, in Washington. Kubiak hired former Denver offensive co-ordinator Rick Dennison to replace Shanahan and former Atlanta offensive co-ordinator Greg Knapp to become Houstons quarterbacks coach. Dennison worked on the Broncos staff during Kubiaks 11 years as Denvers offensive co-ordinator, and Knapp coached Schaub for three seasons with the Falcons. The highest-profile assistant brought to Houston was Phillips, the veteran son of the late Bum Phillips and a former head coach in Denver, Buffalo and Dallas. Last year, the Texans announced contract extensions for both Smith and Kubiak, rewarding them for taking the team to the playoffs last year for the first time. Kubiaks three-year agreement has him under contract through 2014. McNair said at the time he offered Kubiak a four-year deal, but the coach preferred to make it for three. Kubiak made his mark as Denvers offensive co-ordinator under Shanahan, winning two Super Bowls. An eighth-round pick out of Texas A&M, he spent nine years as John Elways backup. He finished his career 4-1 as a starter, all in emergency relief of Elway.

The Arena das Dunas in the northeastern city of Natal sustained minor damage during the protests, but demonstrators stayed away on Sunday and officials said the stadium passed its first test, with only minor adjustments needed going forward. Work was being done until the final moments before the inaugural match, but the doubleheader between local clubs in front of tens of thousands of fans was not affected. Before the matches, local media reported that police arrested two men accused of firing shots at a group of rival fans a few kilometres from the stadium. No one was injured. Demonstrators complaining about the costs of the World Cup destroyed some protective fencing and set fire to temporary tents outside the Arena das Dunas late Saturday. Local media reported security guards fired shots into the air to disperse the crowd. The Tribuna do Norte newspaper said 19 people were detained. The protest was part of a nationwide movement by those oopposed the level of spending on the World Cup.dddddddddddd. About 1,000 people protested in Sao Paulo and smaller demonstrations took place in several other cities. Demonstrators attacked an empty police vehicle, torched a small car and smashed the windows of banks in Sao Paulo. Authorities responded with tear gas and rubber bullets and detained more than 100 people in South Americas biggest city. On its Facebook page, the Anonymous Rio protest group billed "Operation Stop the World Cup" as this years first act against the football tournament. The Confederations Cup was marked by violent protests last year and more are expected during the World Cup. The Arena das Dunas was the seventh World Cup stadium to be completed, with five still being worked on less than five months before the opening game on June 12. Those stadiums are mostly expected to be ready in time, but there is doubt about whether Curitiba will remain a host city as the stadium there is running well behind schedule. Brazil had promised to hand over all 12 World Cup stadiums by the end of 2013. Six of them were ready for the Confederations Cup last year.
