ENGLEWOOD, Colo. -- Gary Kubiak was expected to announce his starting quarterback Tuesday morning for Denvers preseason opener. The Broncos coach instead dragged out the drama another 24 hours.The biggest question at Broncos training camp -- who is the No. 1 quarterback -- is still unanswered. Kubiak and his staff are deliberating whether veteran Mark Sanchez or Trevor Siemian will start at Chicago on Thursday night, with a decision now expected Wednesday.Im holding yall off for one more day, Kubiak said.Sanchez and Siemian are listed as co-No. 1s on the depth chart as neither has shown himself as the clear-cut starter for the Super Bowl champions.Kubiak said he would meet later Tuesday with his staff to decide who would take the first offensive snap Thursday. He said the game plan is to play Sanchez and Siemian a quarter each, and to have rookie Paxton Lynch play the second half against the Bears.What we want to do is put a number on reps and what we want to see from each one of them so that from an evaluation standpoint were looking at things pretty equally, Kubiak said. Thats the most important thing right now.Sanchez, in his eighth year, said the competition is healthy.Im not worried about it, Sanchez said. Its whenever Kubiak is ready to decide. Its his call all the way and we just have to keep competing for the whole season. It doesnt really matter what happens here.The Broncos traded for Sanchez after Peyton Manning retired in March and Brock Osweiler signed with Houston two days later. Siemian, Denvers third quarterback for most of 2015, impressed in offseason workouts to make training camp a quarterback competition.Siemian served as the backup for six games last year when Manning was hurt. He played in one game without throwing a pass. He is more familiar with the offense this year and says his comfort level has grown.I was pretty nervous last year. I wasnt getting a ton of reps, he said. I was trying to get a grasp of the playbooks. In that sense, I think Im a little more comfortable, as in I know my assignments. I know where my eyes need to go. Theres a sense of, `I know what Im doing.Kubiak did say linebacker Von Miller, cornerback Aqib Talib and offensive tackle Russell Okung would not play. Defensive end DeMarcus Ware is on the non-football injury/illness list.Talib returned to practice Monday and increased his workload Tuesday, but he is not ready to play Thursday.Miller said he is physically ready to play, but his mental conditioning is not there yet. Miller had a busy offseason that included tough contract negotiations and several TV and public appearances following his MVP performance in Super Bowl 50.Whenever you take a break from football its a process to get back to the game speed that I want to play at, he said. Im right there, Im ready to go, but the Von I know I can be and I want to be, Im not there yet. A week or two I should be all right.Kubiak isnt worried about Miller or the other veterans not playing Thursday because he said the game is about the backups and getting to hit another team.Were tired of each other, he said. Weve been going at each other for a long time. Its time to go with each other.Game notesKubiak said OL Ty Sambrailo (elbow) is working out and being evaluated on a week-to-week basis. ...

Rory McIlroys best finish came in 2008, when he ended the week in seventh spot The 27-year-old is the only player in the worlds top five yet to register a worldwide win in 2016, but McIlroy feels his game is in good shape to challenge for victory this week.My performances in this event, obviously over the past three years, but going beyond that, havent been what I would want, McIlroy said.I want to really change that this week with a good performance and I feel like my game is in good enough shape to do that.Im coming off a couple of decent weeks in the States where I felt like I played better than what the results suggested, so Im looking forward to the week. McIlroy posted a second-round 64 at TPC Sawgrass last week The K Club here is a golf course where I feel like I can do well on. Itt sets up well for me.dddddddddddd It would be huge (to win). I think anyone that plays professional golf, they dream of winning their home open.You dont get very many opportunities to do it, so it would be very special. Its definitely one tournament that is missing from my CV that I would love to add.McIlroy tees off alongside Andy Sullivan and defending champion Soren Kjeldsen for the opening two rounds in Kildare, while Masters winner Danny Willett has been grouped with Lee Westwood and Rafa Cabrera Bello. Andy Sullivan and Rory McIlroy went head-to-head in the final round of Novembers DP World Tour Championship The four-time major champion posted an opening round 80 and missed the cut at Royal County Down 12 months ago, but feels he has learnt from last years first stint at tournament host.I think there was times where I spread myself a little bit too thin last year with a lot of commitments and weve tried to scale that back a little bit this year, he added. I want to try to make this one of the best tournaments in the world and I feel like weve made a few good strides towards doing that.Once the tournament starts I really dont have many other commitments, so Im trying to really focus on the tournament when we get going.Watch the Irish Open throughout the week live on Sky Sports 4 - your home of golfAlso See:McGInley: Rory the man to beatWillett learning champion lifeIrish Open: 2015 highlightsGolf live on Sky Sports 4 ' ' '
