The Jacksonville Jaguars frittered away a 10-point fourth-quarter lead in losing 24-20 to  Tom Brady  and the New England Patriots in the AFC championship game  yet their unraveling really began in the final 2Â½ minutes of the first half.
Danny Amendola's fair catch of Brad Nortman's punt at his 14 came with 2:02 remaining  which essentially gave  Brady  and Belichick an extra timeout with which to work.
On first-and-10 from his 40   Brady  threw a long pass for Rob Gronkowski  who was injured when  he  got popped by Barry Church on a helmet-to-helmet hit. Church was called for unnecessary roughness  putting the ball at the Jacksonville 45.
 Brady  started pushing the ball downfield to  his  receivers and the New England defense took away the short middle and dared Bortles to start making plays downfield  too.
While Bortles managed a single first down in the fourth quarter   Brady  came through with a pair of TD throws to Amendola.
Amendola had the crucial catch on the first TD drive  hauling in a 21-yard pass from  Brady  on third-and-18 in front of safety Tashaun Gipson  who said he figures he'd break up that pass nine out of 10 times.
It was  vintage Brady   too.
" He  is the greatest quarterback to ever play this game " Gipson said. "You can never have a safe lead with 12 at the helm. We knew we had to keep our foot on the gas."
The Patriots' comeback set up a Super Bowl 52 showdown with the Philadelphia Eagles  who were miffed last week when the NFL mistakenly released an ad that featured  Brady  and Case Keenum with the Super Bowl trophy between  them   signifying a New England-Minnesota matchup.
Instead  it'll be Nick Foles and the Eagles  who routed the Vikings 38-7 in the NFC championship game  trying to dethrone  Brady  and the Patriots.

And with a mangled racket and plenty of kicking and screaming  including a couple of arguments with the chair umpire  then a postmatch parting shot at a line judge Safin called "a little bit too blind."
 Safin used to rant about disliking tennis on grass  and he once complained about the high price and low quality of food at the players' restaurant at the All England Club. Well  he doesn't have to worry about any of that again after bowing out in his final Wimbledon with a 6-2  3-6  7-6 (4)  6-4 loss to Levine.
 After confirming this would be his last appearance at the grass-court Grand Slam tournament -- Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
 "He's an amazing player  and I'm still kind of feeling weird right now that I just beat Safin  because I've always watched him play on TV " said Levine  who turned pro in 2007. "I just kind of went out there with nothing to lose and played some good tennis."
 Levine was a teen when Safin burst onto the scene as a brash  big-hitting 20-year-old who knocked off Sampras to win the U.S. Open.
 "I really had to ... focus on playing against the ball and not worrying about  'Oh  wow  I'm playing against Marat Safin on the other side of the court '" Levine said. "Because then things could have gotten a lot more interesting."
 As is his wont  Safin made things interesting enough. In the early going  he broke his racket by spiking it on the court.
 Leading 4-3 in the third-set tiebreaker  Safin hit a shot near a line that was ruled out. Afterward  Safin said: "Thanks for the guy who made the call. I want to say hello to him. Too bad that he was a little bit too blind."
 In the fourth set  Safin told the chair umpire he could check for chalk on the ball to confirm a call. Rebuffed  Safin added: "So all players are stupid?"
 Safin reached at least the semifinals at all four majors  including at Wimbledon last year  but he has been criticized for not living up to the potential stored in his 6-foot-4 (1.93-meter) frame -- about 7 inches (18 centimeters) taller than Levine.
 "In the history of tennis  everybody's an underachiever " Safin said. "Agassi should have been winning  I don't know  15 Grand Slams. Sampras should have been winning 20 Grand Slams. Federer should be winning -- already should have 25."
 "I should probably have (won) a couple of more " he said  "but I'm pretty satisfied with what I did."

Russia and Belarus on Wednesday signed a new deal on Russian oil deliveries to Belarus  Russian Deputy Prime Minister Igor Sechin said  ending a month-long dispute that had raised fears European supplies could be threatened.
 "Today a large number of documents have been signed " Sechin told Russian President Dmitry Medvedev at a meeting  in comments published on the government web site.
 Sechin said the documents signed involved changes to previous agreements on the delivery of crude oil to Belarus and the method of setting prices for the sale of Russian oil.
 Sechin said he and his Belarussian counterpart had also signed a joint declaration pledging uninterrupted transit of Russian oil across Belarus to third countries.
 Sechin said that Russia agreed to compromise on "harsh" conditions because of the special relationship between the neighbouring Slavic countries.
 "The position of the Belarussian side was very harsh for us. We agreed to a number of compromises  bearing in mind the special relationship with a brother republic  with the people of Belarus " Sechin said.
 Sechin called the signed documents "very balanced" and "representing a compromise."
 In televised comments to Sechin  Medvedev said the Russian position was to "give our Belarussian partners the opportunity to work by providing delivery for internal use at a reduced price and on the other side to guarantee transit."
