<a href="https://www.cricketcountry.com/teams/Sri-Lanka" target="_blank">Sri Lanka</a>'s opener <a href="https://www.cricketcountry.com/players/Sadeera-Samarawickrama" target="_blank">Sadeera Samarawickrama</a> has been out of action of the final Test against <a href="https://www.cricketcountry.com/teams/india" target="_blank">India </a>after being struck on the helmet while fielding at forward short-leg on Day One. He has not taken the field since then, and will be given green signal only after the neurologist gives him a nod. Interestingly, Samarawickrama was hit for the second time in a row by <a href="https://www.cricketcountry.com/players/Murali-Vijay" target="_blank">Murali Vijay</a>. He had earlier taken a blow at Nagpur, and again came the came way of Vijay's line when he attempted a sweep shot at Feroz Shah Kotla on Saturday. <p></p> <p></p><strong>Says Sri Lanka's team manager</strong> <p></p> <p></p>"We will do a first test tonight (Sunday) with him in the gym. If he comes okay from that and the medical staff is happy, he'll have a hit tomorrow morning. Then the doctors will look at him and if things go right, he will get the green light to play. <p></p> <p></p>He is feeling fine. It's because of a concussion, we just have to be careful after what happened to Phil Hughes. There are some guidelines that we have got to follow. We are working with a neurologist because the team doctors from Sri Lanka told us to only deal with the neurologist and to get the green light from him. <p></p> <p></p>We had a neurologist in the changing room this afternoon. He worked with Sadeera and he gave us the green light so that Sadeera could start running. What we are looking at is, if he starts running and if he gets a headache and feels vomitish, we have to stop him immediately. He says he is fine and actually wanted to open the batting. But we are taking all the precautions." <p></p> <p></p><strong>Cricket has learned its lessons the hard way</strong> <p></p> <p></p>Umpires have become extra cautious in relation to any injury in the head or neck. It is an aftermath of what had happened back in November 2014 when Australia's young talent, Phil Hughes, lost his life after being hit in the head during a Sheffield Shield encounter in Australia.
