ESPN senior NFL analyst Chris Mortensen, who was diagnosed with Stage IV throat cancer earlier this year, said Wednesday that he doesnt have a specific date hell return to work, but he plans to be part of the networks NFL coverage as the season gets underway.I received very encouraging news last week from my oncologist team of doctors at M.D. Anderson Cancer Center that now enables me to completely focus on recovery rather than treatment, Mortensen said in a statement released by ESPN. The Stage IV throat [oropharyngel] cancer that was diagnosed in early January and treated with intensive chemotherapy and radiation has been virtually reduced to zero detection of the disease through the latest scans and exams.I do have scheduled exams and scans during the next three months to monitor my status but my oncologists have directed me to recover and rehab from the treatments that have resulted in lengthy hospitalization, significant weight loss, strength, endurance and related health issues. I am following instructions to overcome these challenges.My return-to-work status has variables with no definitive target date but I anticipate being able to participate in NFL coverage on a limited basis as the 2016 season gets underway.Mortensen took a leave of absence from ESPN in January and missed the Super Bowl.It has been a long and difficult road for Mort since he was diagnosed, so hearing his positive news is very encouraging, ESPN senior coordinating producer Seth Markman said. As we have said all along, when Mort is able to return, his chair on our set will be waiting. He is a beloved member of our ESPN team, and we have really missed him these past few months.Mortensen, who has been with ESPN since 1991, won the prestigious Dick McCann Award at this years Pro Football Hall of Fame induction ceremonies.My wife Micki and I want to express our deepest gratitude and humility from the outpouring of love we have received from family, friends, colleagues, the NFL community and beyond, as well as ESPNs unwavering support. Our hope remains rooted in our deep faith in God and we continue to be grateful to our caring team at M.D. Anderson and my local personal physicians.We also want to encourage everyone to support various cancer causes such as the V Foundation -- we can testify that these specific organizations are justifiably necessary and righteous to families who encounter this insidious disease.

LONDON -- With Chelsea leaking goals too easily, Antonio Conte didnt have to search far for the solution.The Italian manager merely implemented the tactics that served him well with Juventus and his national team.Chelsea hasnt conceded a goal in the Premier League and has won all four games since Conte removed a defender from its typical four-man back-line. And, with four successive victories since the tactical tinkering, Chelsea has clambered up the standings to join the chasing pack.Manchester City, Arsenal and Liverpool are only separated by goal difference, and Chelsea, which hosts Everton on Saturday, is a point behind. Its some revival for a team that was on its knees last season, when the reigning champions collapsed and Jose Mourinho was fired.Gary Cahill has been featuring on the left of the back three with David Luiz in the center and Cesar Azpilicueta on the right.Every player has worked hard on the shape the manager has brought in and we are getting the rewards, Cahill said. It is all right having the shape. It is also to do with having the players with the mentality to go out and do the business when we need to.We have the flair players to go out and create and score goals, but we also need them to dig in and defend well.The turning point was the Sept. 24 loss to Arsenal, when Chelsea had conceded three goals before halftime. Switching to three at the back for the second half shored up the defense and prevented a heavy defeat. Within weeks, Chelsea was delivering a humbling of its own by beating Manchester United 4-0 in the biggest sign that Contes 3-4-3 is flourishing.The central defenders on the right and the left must be very fast and aggressive, Conte said. The players that play in the middle of the three defenders must be more tactical, must reflect more and find the right position, and also call the line up and down.Saturdays opponent, Everton, is only four points behind Chelsea and in sixth place despite an erratic spell in recent weeks. The highlights have been holding Manchester City to a 1-1 draw and beating West Ham, but losses to Burnley and Bournemouth could prove damaging to Evertons ambitions to qualify for the Europa League.Here are the other talking points this weekend:---NORTH LONDON DIVIDEArsenal and Tottenham head into Sundays derby after a week of contrasts in the Champions League.
