The NFL has announced seven winners of its second Head Health Challenge.Each will receive $500,000 for its project, and five could receive up to an additional $1 million in 2015 based on their progress. The winners were selected from nearly 500 proposals that were submitted between September 2013 and February 2014 from 19 countries.The program is sponsored by the NFL, GE and Under Armour and is part of a four-year, $40 million initiative to help develop diagnoses and treatments of mild traumatic brain injury.Each of these seven winners will help advance the science toward our shared goal of making sports safer, NFL Commissioner Roger Goodell said in a statement. New materials, equipment designs and technology breakthroughs will better protect athletes, no matter what sport they play.The program winners are:— Army Research Laboratory, Baltimore. The ARL created rate-dependent tethers that provide resistance during high-speed events. The proposal called for the materials to be connected from the head to torso, allowing for voluntary movement during sports while minimizing sudden accelerations caused by high-speed collisions.— Emory University. Researchers and engineers at Emory and Georgia Tech developed a prototype medical device that can screen for and assess concussions in real time. The device includes a headset and hand-held device to assess symptoms, cognitive function, balance and eye movements.— UCLA. UCLA and Architected Materials, Inc. are developing a new energy-absorbing helmet liner that would absorb significantly more energy than current designs. The proposal plans to use a new 3D printing platform to develop real-time responsive helmet technology.— University of Miami. Its Miller School of Medicine, in collaboration with the University of Pittsburgh School of Medicine, is developing goggles to measure precise eye movements and assist in identifying mild traumatic brain injury in real time and more accurate concussion diagnosis.— University of Washington. Through its commercial partner, VICIS, Inc., the school is developing a new impact-absorbing helmet with a structure and materials to better protect against head injuries. The group developing the helmet includes engineers, neurosurgeons and public health experts.— Viconic, Inc., Detroit. Viconic is researching development of an under-layer for synthetic turf fields to make them safer. The goal is to provide the synthetic turf industry a tool to maximize safety and minimize cost.— University of New Hampshire. Researcher Erik Swartz is leading a study to evaluate the effectiveness of a helmetless training system for tackling. The study will examine whether implementation of this technique results in player behaviour change and reduces injury risk when shoulder pads and helmets are used.___AP NFL websites: www.pro32.ap.org and www.twitter.com/AP_NFLAlex Oxlade-Chamberlain Arsenal Jersey . Beckham says "nothing has been confirmed yet, but its something I am very excited about." He adds that "Miami is something that really excites me because there is a great energy down there.

There are some early surprises in the race for the Hart Trophy, but two of the contenders are the leagues biggest stars over the past decade. There are many more players in contention for the awards than just the three that Ive named, and a good or bad week can easily alter the landscape, but through the first 20 or so games of the NHL season, this is how the awards races look to me. Kieran Gibbs Jersey . -- At the beginning of training camp, Andrew Bogut set a goal to play all 82 regular-season games and regain his place among the NBAs best centres. Granit Xhaka Arsenal Jersey . Now, Sarah Burkes legacy will live on in Canadas Sports Hall of Fame. Burke, who tragically died at age 29 from a training accident in 2012, headlined the 2014 class named for induction Wednesday.TAMPA, Fla. -- Alex Rodriguezs spring training locker has been kept open by the New York Yankees. Suspended for the season for violations of baseballs drug agreement and labour contract, Rodriguez had used the stall just to the side of the back entrance of the clubhouse at Steinbrenner Field.

Rodriguez is eligible to return next year, when he turns 40, and has three seasons remaining on his record $275 million, 10-year contract. Masahiro Tanaka, the Jappanese pitcher signed to a $155 million, seven-year deal, was given the locker used by Mariano Rivera, who retired after last season.dddddddddddd Speaking through a translator, Tanaka said he was informed of that by a Yankees staff member. "Im not really sure if I should be here," he said of the stall. Reliever Shawn Kelley was given the locker of retired pitcher Andy Pettitte.
