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. Jusuf Nurkic Jersey . 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.

If Chad Johnson was hoping for a regular parking space at the home of the Montreal Alouettes, the GMs spot is taken for a few more years. The Als gave Jim Popp a contract extension on Thursday, ending worries the team would suffer added brain drain after losing Marc Trestman to the Chicago Bears. ?Popp has frequently been a candidate for a range of front office jobs including the GM role with the NFLs Carolina Panthers, a team headquartered just a 30-minute drive from his home in North Carolina. Since Popp helped move the Baltimore Stallions north in 1996, the Alouettes are the winningest team in the CFL.? Popp has been the only constant, but sources close to the team admit he had been hoping and planning on returning this season in the dual role of coach and GM.? Entering the final year of his contract, he was surprised by the hiring of Tom Higgins -- a CFL sideline veteran and former director of officiating -- as the teams new head coach. Some have speculated Popps signing of the NFL star formerly known as Ochocinco was as much about putting himself back in the front office job spotlight south of the border as it was gettinng the Bengals all-time leading receiver for Alouette quarterbacks.

But Popp has never been shy about taking a chance on NFL talents past their prime: witness Ahman Green, Quincy Carter and the infamous Lawrence Phillips -- who helped Popp and the Als end a 25-year Grey Cup drought back in 2002.

Popps master stroke in recent years was turning an out-of-fashion offensive guru named Marc Trestman into the hottest coaching commodity to come out of Canada in recent decades.? The immediate task for Popp this season is keeping the Als competitive after the retirement of Anthony Calvillo, as Troy Smith, the 2006 Heisman Trophy winner, will attempt to solidify his teams tentative start with a victory against Winnipeg Friday night.? Popp will soon be packing bags for his annual NFL training camp scouting missions in about two weeks, when hell see his first round selection in the CFL Draft, David Foucault now a rookie hopeful with the Panthers.
