Umpire Paul Reiffel will not stand for the remainder of the Mumbai Test after suffering concussion because of a blow to the back of the head on the opening day.Reiffel was helped off the field by Englands medical staff and went to hospital where tests cleared him of serious injury, but he was advised to rest. Marais Erasmus, who was the TV umpire, will continue in the on-field role for the rest of the match.*An ICC statement said: Paul Reiffel underwent precautionary tests yesterday, which came back all clear. Paul, however, has been advised to rest, which is the normal course prescribed following a concussion. As such, he will not take any further part in the Mumbai Test and has been replaced by Marais Erasmus.The accident took place in the 49th over of Englands innings, when Keaton Jennings worked R Ashwin past the square leg. From three-fourths of the way to the fence, Bhuvneshwar Kumar lobbed a throw back to Cheteshwar Pujara, who stood between Reiffel and the stumps. The throw didnt have enough power, and Pujara seemed to warn Reiffel late, leaving him time only to duck. Had Reiffel stood upright the ball might have glanced the top of his head; but now it hit the sensitive area on the back of the head.The other umpire Bruce Oxenford, who wears an arm guard in limited-overs cricket, rushed to provide Reiffel shade with his hat and the England medical team looked after the 50-year-old umpire as he collapsed to the ground. Play was held up for 10 to 12 minutes shortly before the scheduled afternoon drinks break. Erasmus took Reiffels place on the field as he walked off for a medical examination.It helped that there was an understudy for the third umpire: C Shamshuddin, who has stood in ODIs, was at the ground as part of a programme to train local umpires on the DRS. Shamshuddin, who was better versed with DRS protocols than fourth umpire Nitin Menon, moved into the TV umpires seat.Reiffel is scheduled to be an on-field official during the final Test in Chennai.* December 9, 2.15pm IST: This story was updated with news of Paul Reiffel not returning for the Test Teemu Selanne Jersey .

Jolyon Palmer says he feels lucky to have been given a chance to race in Formula One this year by Renault, despite enduring a difficult season.Renault sits ninth in the constructors standings going into the second half of the season and has recorded just six points so far in 2016, after Kevin Magnussens seventh place finish in Russia. Palmer has yet to score a point during his debut F1 campaign, coming closest at the Hungarian Grand Prix, where a late spin dropped him outside of the top 10.Palmer believes there is no reason for him to feel unlucky to be in an uncompetitive car, having waited so long to get his chance to race in F1.I dont feel like that specifically is unlucky, the Briton said. I feel like pretty much a lot of everything else this year has been unlucky but we knew that it was going to be quite tough this year. I expected that we would be kind of where we are, Im still very happy.I think that Im lucky in the grand scheme of things with Renault becauuse they are a manufacturer team.dddddddddddd Theyve got huge resources and they will be champions in the future so its better to be here than to be a driver in some teams that are doing a bit better currently.Following a difficult start to life in F1, rumours began circling that Palmer could lose his seat to Mercedes junior and former Renault reserve driver Esteban Ocon before the end of the season. Such talk has been cooled by the confirmation that Ocon will replace Rio Haryanto at Manor from the Belgium Grand Prix.The 2014 GP2 champion says he has not let speculation about his future distract him from the job at hand.Nothing changes, Im not fussed. Im used to them [rumours] anyway now its not a complete shock. I know the situation here anyway, Im doing my best and regardless of what anyone is saying. Ive got to do my job in the car. ' ' '
