Lance Armstrong has pulled out of a much-hyped interview before an audience in Ireland, citing legal reasons, organisers have said.The American athlete, who was stripped of his seven Tour de France titles over doping, was due to appear at a sports and technology conference in Dublin on Friday.An on-stage interview at the widely-publicised ticket-only event in the Irish capitals RDS arena was to be followed by a 45-minute question and answer session open to the crowd.However, organisers One Zero said Armstrong cancelled with less than 24 hours to go on the advice of his legal team, due to an upcoming court case brought against him on behalf of the US Postal Service.Rob Hartnett, of One Zero, said: We are extremely disappointed that Armstrong has withdrawn at the last minute from appearing at One Zero.He has let us down, he has let his fans down and he has let down those that wanted to hear him openly discuss his past and the future of sport.One Zero said Armstrong had been contracted to speak at the event since August.In a statement on Thursday evening, they said they were acutely aware of the pending legal case and addressed the issue during negotiations some months back.Armstrong did a broadcast interview with an Irish radio station earlier this month.

Umberger scored twice to lead the Blue Jackets to a franchise-record for consecutive wins with a 5-3 victory Tuesday night over the Los Angeles Kings. The Cleveland Browns are the lone remaining winless team in the NFL.The Cincinnati Bengals are part of a different list -- considered one of the leagues biggest underachievers.The Bengals (2-4) have dropped four of their past five games and attempt to break out of their doldrums when they host the lowly Browns (0-6) on Sunday (1 p.m. ET, CBS).Cincinnati expects to be part of the postseason for the sixth consecutive season but the slow start threatens to halt that streak.The Bengals edged the New York Jets in their opener before things disintegrated. Three of Cincinnatis losses have been by 12 or more points, including last Sundays 35-17 setback against the New England Patriots.Were kind of behind right now, with the way this season has gone, and weve got to get it back on track, quarterback Andy Dalton said. You cant try to do too much, youve just got to play your game and do that to the best of your ability. You cant try to do more than you need to. Thats the biggest thing: you cant press.Bengals coach Marvin Lewis has been preaching that theres no reason to panic. He outlined to his squad to just stay the course and, well, play better.We have to play good fundamental football, Lewis said. We have to out-play the other team, out-execute them, out-score them and not have negative plays. Our margin for error has not been very good thus far this season so we have to create our breaks.First-year Cleveland coach Hue Jackson, a close friend of Lewis who spent the past four seasons on Cincinnatis coaching staff, can relate to a lack of breaks.The Browns are on their third quarterback in rookie Cody Kessler after losing Robert Griffin III (shoulder) and Josh McCown (collarbone) to injuries. Cleveland suffered a big defensive loss when free safety Jordan Poyer suffered a lacerated kidney in last Sundays 28-26 loss to Tennessee.He was playing well, Jackson said of Poyer. Its is a blow for us because he is one of our better players.Kessler enjoyed a strong performance in the loss to the Titans by passing for 336 yards and two touchdowns.The former USC standout was a third-round draft pick due to questions about his arm strength. He said he isnt concerned with what the critics say but is fixated on how to help end Clevelands longstanding losing ways -- which includes nine consecutive losses and 16 of 17 dating back to October of last season.dddddddddddd.I take it very personal, as do a lot of guys in this locker room, Kessler said of the losses. It just makes you compete that much harder and keep working harder because we have been really close in some of these games.We just have to put together a full game and I have to put together a full game and a complete game and just continue to keep working. Obviously, it will get to you, but you cant let it knock you down. You cant let it knock you back. You have to stay positive and keep moving forward.The Browns are averaging 110.7 yards per game on the ground but have struggled the past two games -- averaging just 33.5 yards in losses to the Titans and New England Patriots.Cincinnati ranks ninth in defending the run (89.8) and dodged a bullet when controversial linebacker Vontaze Burfict was fined $75,000 on Wednesday but didnt draw a suspension for an incident against New England last Sunday.Burfict was disciplined for delivering an apparent stomp to Patriots running back LeGarrette Blount during a pileup of players. Burfict reportedly is appealing the fine and Lewis is supporting him.We were not in the wrong here, in my opinion, Lewis said. And its unfortunate. Thats what I have told and stood on and will continue to.Burfict missed the first three games of this season due to a suspension for his repeated violations of safety rules, including his actions during last seasons playoff loss to the Pittsburgh Steelers.Defensive end Carlos Dunlap (four sacks) has played well for the Bengals, who will look to silence a Cleveland offense averaging 18.8 points, tied for 26th in the NFL.Cincinnatis offense is faring worse at 18.2 points per game (29th) despite Dalton ranking third in the NFL with 1,757 passing yards and receiver A.J. Green corralling an NFL-best 42 catches.The Bengals could have standout tight end Tyler Eifert at their disposal for the first time this season. Eifert, who caught 13 touchdown passes last season, returned to practice on Wednesday after missing the first six games due to ankle and back injuries. ' ' '
