PHILADELPHIA -- The NFL agreed Wednesday to remove a US$675 million cap on damages from thousands of concussion-related claims after a federal judge questioned whether there would be enough money to cover as many as 20,000 retired players. . A revised settlement agreement filed in federal court in Philadelphia also eliminates a provision that barred anyone who gets concussion damages from the NFL from suing the NCAA or other amateur football leagues. In January, U.S. District Judge Anita Brody had denied preliminary approval of the deal because she worried the money could run out sooner than expected. The settlement, negotiated over several months, is designed to last at least 65 years and cover retired players who develop Lou Gehrigs disease, dementia or other neurological problems believed to be caused by concussions suffered during their pro careers. More than 4,500 former players have filed suit, some accusing the league of fraud for its handling of concussions. They include former Dallas Cowboys running back Tony Dorsett and Super Bowl-winning Chicago Bears quarterback Jim McMahon, who suffers from dementia. "This agreement will give retired players and their families immediate help if they suffer from a qualifying neurocognitive illness, and provide peace of mind to those who fear they may develop a condition in the future," plaintiffs lawyers Christopher Seeger and Sol Weiss said in a statement. The original settlement included $675 million for compensatory claims for players with neurological symptoms, $75 million for baseline testing and $10 million for medical research and education. The revised settlement eliminates the cap on overall damage claims but retains the payout formula for individual retirees. A young retiree with amyotrophic lateral sclerosis, or Lou Gehrigs disease, would receive $5 million, a 50-year-old with Alzheimers disease would get $1.6 million, and an 80-year-old with early dementia would get $25,000. Even with the cap removed, both sides said they believe the NFL will spend no more than about $675 million to ex-players. Brody will decide later whether to accept the new settlement terms. Critics of the deal have said the league, with annual revenues topping $9 billion, was getting off lightly. Lawyers for the plaintiffs said the settlement avoids the risk of a protracted legal battle. The proposal does not include an admission from the NFL that it hid information from players about head injuries. "Todays agreement reaffirms the NFLs commitment to provide help to those retired players and their families who are in need, and to do so without the delay, expense and emotional cost associated with protracted litigation," NFL Senior Vice-President Anastasia Danias said in a statement. . - Even with his surgically repaired back still nowhere near perfect, defending champion Andy Murray needed only 73 minutes to beat Jo-Wilfried Tsonga 6-4, 6-1 at the Sony Open on Tuesday and set up a quarterfinal with Novak Djokovic. .

PAUL, Minn.Tuscaloosa, AL (Sports Network) - Trent Richardson recorded 126 yards on 17 carries and added 85 yards and a touchdown on three receptions as third-ranked Alabama took a 38-14 victory over No. 14 Arkansas in the Southeastern Conference opener for both teams. AJ McCarron connected on 15-of-20 passes for 200 yards and two scores in a winning effort for Alabama (4-0, 1-0 SEC) "It was a great team win. When I say team win, Im talking about all the players, all the fans, all the people in the organization who contribute to the success of the team in every way," said Alabama head coach Nick Saban. "It was a physical game out there. It was two good football teams out there playing" Tyler Wilson went 22-for-35 for 185 yards and two touchdowns through the air for Arkansas (3-1, 0-1). Dennis Johnson and Cobi Hamilton caught TD passes for the Razorbacks, who failed to reach 4-0 for the first time since 2003. Alabama took the opening drive of the game 80 yards down the field for the early lead on a 37-yard touchdown pass by McCarron to Michael Williams on a fake field goal. Richardson carried the ball four times for 32 yards on the drive. After trading punts, Wilson led a 12-play, 63-yard drive to tie the game at seven. Ronnie Wingo Jr. had a 26-yard touchdown run called back on a holding call, but Wilson hit Johnson for a 10-yard score four plays later. The Crimson Tide took the lead back with under six minutes to go in the second quarter on Jeremy Shelleys 20-yard field goal. Richardson totaled 58 yards of offense on the 77-yard drive, but the Razorbacks defense held on a 1st-and- goal at the one to fforce the field goal. . DeQuan Menzie then intercepted Wilson on a third-down pass attempt and ran it back 25 yards for a score to give Alabama a 17-7 lead at the half. Alabama forced an Arkansas punt on its first possession of the second half and Marquis Maze weaved his way down the field on the return for an 83-yard touchdown. The Razorbacks were held to a three-and-out, and Richardson took a screen pass 61 yards for a score on the Crimson Tides second play of the drive with just under 10 minutes left in the third quarter. Johnson returned the ensuing kickoff 30 yards and Wilson hit Wingo for a 39- yard pass before connecting on a 19-yard score to Hamilton in the back of the end zone to bring Arkansas within 31-14. But the Razorbacks were stopped on a 4th-and-one after forcing an Alabama punt, and a Brad Smelley 15-yard catch and a Richardson 25-yard rush set up Eddie Lacys four-yard rushing touchdown to give the Crimson Tide back their 24-point cushion. "They beat us in all three phases of the game," Arkansas head coach Bobby Petrino said. "They made big plays and we didnt. They hurt us with the fake field goal, the punt return for a touchdown and the screen pass for a touchdown." Game Notes Alabama linebacker C.J.
