MANAUS, Brazil -- Mario Mandzukic scored two goals Wednesday to keep Croatia in the mix at the World Cup with a 4-0 win over 10-man Cameroon, which will be going home after the group stage. Mandzukic, who returned to the team at the Arena da Amazonia after sitting out the opening loss to Brazil through suspension, headed in a corner from Danijel Pranjic in the 61st minute and then knocked in a rebound in the 73rd of the Group A game. Ivan Perisic also scored one goal and made another for Ivica Olic. Cameroon was reduced to 10 men after midfielder Alex Song was given a red card for elbowing Mandzukic in the back in an off-the-ball incident in the 40th minute. Cameroon started without the injured Samuel Etoo, the teams best player. And the frustration within the team boiled over in injury time when Benoit Assou-Ekotto head-butted teammate Benjamin Moukandjo in front of their goal. "Its unimaginable. I saw this happen and I need to find out exactly what happened, why exactly these two players exploded," Cameroon coach Volker Finke said. "I really hate to see that. Its not the image of Cameroon I want to project." Croatia now has its future in its own hands. If the 1998 World Cup semifinalists beat Mexico on Monday, they will guarantee themselves a spot in the second round. The Mexicans will advance with only a draw. Cameroon is out, however, and can only play spoiler in its final match against five-time champion Brazil, also on Monday. If the 1990 World Cup quarterfinalists beat Brazil, the host country could still advance or be forced out of the tournament on goal difference. Darijo Srna started the move for the first goal, whipping a cross into the area from the right in the 11th minute. Mandzukic and Nicolas Nkoulou then collided while going for it, but the ball popped loose to Perisic. The Croatia midfielder stepped up and coolly slid the ball into the path of Olic to tap in. Perisic did it all himself early in the second half, beating Cameroon defender Dany Nounkeu to a long pass from goalkeeper Charles Itandje and taking it all the way back to where it came from. Perisic, with Nounkeu chasing him, ran into the area down the left and gave himself a tough angle before slipping his shot between Itandje and the near post in the 48th. Mandzukic was left unmarked to head home Croatias third goal and followed up with the simplest of tap-ins when Itandje spilled a shot from Eduardo. Cameroon knew it needed points against Croatia, and the team came out fast in an effort to take the early lead. Several dangerous attacks down the right flank caused concern to the Croatia defence early, but none of them materialized into any real danger. A few late chances came close, but nothing got past Croatia goalkeeper Stipe Pletikosa. "The team tried with only 10 players, but the second goal arrived very early in the second half, unfortunately," Finke said. "After that it was an uphill battle." The loss of Etoo, who came to Brazil with a right knee injury, was a blow to the team, however. Although Cameroon still went on the attack even without their best attacker, the finishing class of the former Chelsea and Barcelona striker was missing. The loss of Song didnt help, either. The midfielder, well away from the ball, was running back from the Croatia end when he lashed out and elbowed Mandzukic in the back. Referee Pedro Proenca of Portugal immediately pulled out his red card and sent Song off. Song is the cousin of Cameroon great Rigobert Song, one of only two players to be sent off at two different World Cups. The other is Zinedine Zidane. Chance Adams Yankees Jersey .

Bernie Williams Jersey . -- Antoine Bibeau bought the Val-dOr Foreurs valuable time at the Memorial Cup with his 51-save shutout Friday.Newark, NJ (SportsNetwork.com) - Devils president and general manager Lou Lamoriello has come up with a unique solution to fix the teams coaching situation. After firing head coach Peter DeBoer on Friday, Lamoriello announced on Saturday that he will join Scott Stevens and Adam Oates behind the bench. Oates will have full control of the forwards, while Stevens will have full control over the defensemen. Neither Oates nor Stevens was given an official title. New Jersey plays the New York Rangers at Madison Square Garden on Saturday. Lamoriello said that it would be unfair to ask one person to come in and be the head coach for the rest of the season. Assistant coach Dave Barr was dismissed. This marks the third time Lamoriello has been behind the bench for New Jersey, all of them coming after he fired a coach in-season. He has posted an impressive 34-14-5 regular season record in two brief stints dating back to 2005-2006 and 2006-2007. DeBoer led the Devils to a 12-17-7 start. He wwas in his fourth season as New Jerseys coach.dddddddddddd. The Devils were 114-93-41 under DeBoer. DeBoers best season in New Jersey was his first as he guided the team to a 48-28-6 record in 2011-12. The Devils represented the Eastern Conference in the Stanley Cup Finals, but lost to the Los Angeles Kings in six games. Oates and Stevens are both in the Hockey Hall of Fame as players, with the latter man known best for time spent as captain of the Devils from 1992 until his retirement following the 2003-04 season. He helped lead New Jersey to three Stanley Cup titles during that time. Both Oates and Stevens previously served as assistant coaches for the Devils. Oates was on DeBoers staff when the club reached the 2012 Cup Finals before leaving to become the head coach of the Washington Capitals. He was fired by the Capitals last spring after two seasons with the club. Stevens served as an assistant under DeBoer in 2013-14 before stepping down prior to this season. ' ' '
