NFL Jerseys Store .Poljak is a strong contender to become Newcastles stand-in captain for at least the next few weeks after skipper Nigel Boogaard tore ankle ligaments in their 2-1 defeat to Melbourne City on Thursday.Its not yet clear how long Boogaard will be out for, but he was the player the Jets could least afford to lose following injuries to defenders Lachlan Jackson (ankle), Ben Kantarovski (knee) and Daniel Alessi (knee).Poljak, however, is staying positive, writing their injury curse off as bad luck and insisting the Jets are headed in the right direction.Its just unlucky. Fair enough if they were muscular injuries, youd think maybe somethings (gone) wrong, but its more impact and knocks, he told reporters on Tuesday.You cant really do much about it.It doesnt affect morale - obviously wed like to have more players, especially since the majority of them are starting players and leaders as well, but what do you do?I think weve got pretty good depth this year, well cover them.Former Adelaide United and Sydney FC centre-back Iain Fyfe has been training with the Jets since Monday and is likely to sign an injury replacement contract to act as cover for Boogaard, which would alleviate some of coach Mark Jones defensive headaches.Fyfe, now 34, has been playing in the South Australian NPL with Campbelltown City since 2014.I think the recruitment of Fyfey is quite a good thing for us, hes been vocal in the last couple of days, Poljak said.We have a strong leadership group but unfortunately a (because) couple of injuries, theres less and less experienced players.It does come up to a few of us to lead that and help young players and ourselves.The Jets take on Central Coast in the F3 Derby on Sunday at McDonald Jones Stadium.

RIO DE JANEIRO -- Taekwondo is a Korean martial art that emphasizes kicking.Fully padded fighters compete to see who can land the most kicks. The head and body are legitimate targets and all kicks are scored electronically; fighters wear special sensor socks and kicks to their opponents body protector are recorded only if they are executed with sufficient force, which is calibrated differently for every weight division.For safety reasons, kicks to the head are scored whenever the fighters foot simply touches the opponents head guard or face -- no force is required. Punches to the body are allowed, but not to the head.A match consists of three two-minute rounds and will go into a golden point round if the score is tied at the end of three rounds. At that point, the first fighter to score -- with any technique -- wins. Heres a quick guide to taekwondo scoring.1. Body shots. Kicks to the body score one point. But if they incorporate a spinning technique, like a back kick, they can score three points. Punches to the body score one point.2. Head kicks. Kicks to the head score three points, unless they involve a spinning technique, in which ccase an extra point is awarded. Wholesale NFL Jerseys Online. 3. Penalties. Fighters can be penalized if they withdraw from a fight, are inactive for 10 seconds or fall, even if thats the result of being kicked. Fighters cannot grab their opponents and no kicks below the belt are allowed. Referees have significant leeway, however, on handing out penalties and are encouraged to keep the fight active rather than constantly stopping and starting the action.4. The 12-point gap. Taekwondo fights are automatically suspended if one fighter gains a 12-point lead on the other. That gap is considered too big to claw back and fights will usually be stopped at the end of that round.5. Video replays. Coaches may request a video replay if they feel their fighters technique hasnt been scored or if they think their fighters opponent was improperly awarded points. The decision is made by a panel of taekwondo judges who watch an instantaneous video replay. If coaches lose the challenge, they must surrender their video replay card to the referee.
