SANTA CLARA, Calif. -- Colin Kaepernick says he has received death threats through social media and other avenues since he began to protest during the national anthem last month.Kaepernick said Tuesday he has not alerted San Francisco 49ers team security about the threats and understood that could happen once he began his protest over racial oppression and police brutality in the United States.To me, if something like that were going to happen, youve proved my point, he said. It would be loud and clear for everyone why it happened. That would move this movement forward at a greater speed than what it is even now. Granted, I dont want that to happen. But thats the realization of what could happen.Kaepernicks protest during the anthem became public last month when he sat during the anthem before a preseason game against Green Bay and later explained his reasoning. He has since kneeled before the Niners past three games. The kneeling is meant to show more respect for veterans.Kaepernick has been joined by several other NFL players, U.S. soccer star Megan Rapinoe and scores of high school and college players who have picked up the cause.It has not received universal support, however, and he said he was the target of racial slurs and other insults before last Sundays game at Carolina.Theres a lot of racism in this country disguised as patriotism and people want to take everything back to the flag but thats not what were talking about, he said. Were talking about racial discrimination, inequalities and injustices that happen across the nation.Kaepernick spoke to one of those cases Tuesday, the shooting of an unarmed black man in Tulsa, Oklahoma, last week. Police video shows 40-year-old Terence Crutcher walking away from the officers and toward his SUV last Friday with his hands in the air. He then approaches the drivers side of his vehicle, where an officer shocks him with a stun gun and another fatally shoots him.Officers had been called to the scene to respond to a report of a stalled vehicle.The officer who shot Crutcher, Betty Shelby, was placed on paid leave.His car was broken down, he was looking for help and he got murdered, Kaepernick said. Thats a perfect example of what this is about. I think it will be very telling what happens with the officers that killed him because everybodys eyes will be on this.Kaepernick also gave more details about his plans to donate $1 million to organizations supporting his cause of racial equality. He said he has people currently vetting potential charities to determine the proper ones to donate to and will launch a website detailing his donations and how the money is spent.He plans to give away $100,000 a month for the next 10 months.I want to make sure that not only am I transparent about what Im doing but these organizations are transparent about where the money is going as well, he said.Game notes LB Ray-Ray Armstrong was placed on injured reserve with a pectoral injury. ...

This should be celebrated because it will not always be this way. With the amount of money given to players by their clubs these days, it is a wonder that so many of those teams allow the sport to continue to take away many of their assets so they can play for a different team in the middle of their season.

LONDON -- Doctors could be allowed to watch TV replays of collisions from the touchline next season and then have matches stopped in response to growing concerns about the dangers of concussion.Medics would be given time to assess whether a head injury required a player to be substituted, if the International Football Association Board presses ahead with granting approval at its annual meeting in March.Members of soccers lawmaking body have also told The Associated Press that they are looking to allow coaches to watch feeds of games on the bench for tactical reasons -- provided they arent used to incite protests to officials.Technology is currently only used for in-game incidents to decide whether or not the ball crossed the line.But by the 2018 World Cup, referees could be allowed to gain additional information from an official with access to replays. IFAB is currently overseeing trials with systems that review whether goals have been scored, penalties should be awarded, players should be sent off and cases of mistaken identity.IFAB members say they are not yet ready to approve the live use of video assistant referees, or VARs.However, the March meeting will look to allow medics access to footage during games amid a growing awareness about the dangers of head-impact injuries.Englands domestic rugby league is already trialing pitch-side video reviews of potential concussions.We understand from scientific research and other sports that have introduced it that if you have a much better assessment of the injury, it might be possible, when you see the intensity and the point of contact, to evaluate potential concussions better, IFAB secretary Lukas Brud told the AP.Under protocols introduced two years ago by FIFA, referees can already stop games for three minutes to assess head injuries.We have seen enough examples where potentially if the doctor was able to use video he might have made a decision not to put a player back on the field, Brud said.Incidents that result in a concussion might have been missed by the officials. But any replays reviewed for medical reasons could not be consulted by a referee until VARs are fully approved bby IFAB.ddddddddddddWe want to make sure whatever footage is allowed to be viewed is used for medical purposes only and there are no unintended consequences where footage is then being used for other purposes, Scottish Football Association chief executive Stewart Regan, an IFAB member, told the AP.It could take beyond IFABs annual meeting in March to decide whether to sanction the use of technological aids on the bench by coaches, including tablets with live feeds of games and replays.Theres pragmatism within IFAB as it recognizes that its hard to curb the use of mobile technology.Theres still a little bit of concern in terms where we may end up with this, Regan said. Everyone understands technology is more and more prevalent in football and more and more coaches are using it -- iPads are basically being used to replace pads and paper in many cases.The problem is no one knows if that iPad has a Wi-Fi connection and is being used to transmit images of the game. If those images of the game are used to put pressure on the fourth official or the referee then thats a direction we dont want to go in. We are still looking into it.Turkey coach Fatih Terim was ordered by the fourth official during a friendly against England in May to stop using his mobile phone on the bench in Manchester. Terim remonstrated with the official after England striker Harry Kane appeared to score from an off-side position.Everyone is using phones and tablets and the fourth officials job is not to check constantly what is being used in the technical area but currently its against the laws of the game, Brud said from IFABs base in Zurich.We dont want to create situations where players and coaches are being sent to the stands because they were using a mobile phone ... we need to focus on the behavior when using it. So if have coach with access to replays approaches the fourth official and says a player was offside, the coach can be punished.---Rob Harris can be followed at www.twitter.com/RobHarris and www.facebook.com/RobHarrisReports ' ' '
