Seven Russian swimmers have been allowed to compete in Rio after initially being banned following allegations of a state-sponsored doping operation in their homeland. That decision has sparked vocal complaints from several swimmers, most notably American Lilly King.No statement about Chens reported test was posted to the website of the Chinese Swimming Association, and calls to its offices rang unanswered Friday. FINA, the international governing body of swimming, did not immediately respond to a request for comment.Chens teammate Wang Shun declined to comment after he won bronze in Thursdays 200-meter individual medley.This situation, I dont know the details, Wang said.Li Keke, a spokeswoman for Chinas national anti-doping agency, said she had no additional information on the Chen case.We have noticed media reports about the case.

That, more than the final score, is what the Falcons will take out of their 27-23 preseason loss to the Baltimore Ravens on Thursday night. Ryan threw for 97 yards and a touchdown in four series, and the Falcons led by 16 before the Ravens backups rallied with a 20-point fourth quarter. Atlantas starters bounced back nicely from an opening 34-10 loss to Cincinnati one week earlier. Under Ryans direction, the Falcons pierced Baltimore (2-0) for 11 first downs in 16 1/2 minutes and built a 20-7 lead at halftime. The defence limited the defending Super Bowl champions to three first downs and 13 yards rushing before halftime -- a mere 10 by Ray Rice on eight carries. "The feel on the sideline was that there were a number of areas that we improved on as a football team," Atlanta coach Mike Smith said. "Players that were going to be counting on, I think took a big step from Week One to Week Two." It was 23-7 before Baltimore came back against Atlantas subs. After Tyrod Taylor threw a 5-yard touchdown pass to Tandon Doss to make it 23-20 with 7:52 left, and Asa Jackson scored on a 78-yard punt return with 6:18 remaining. "Were just happy to come away with the win," Rice said. "Our young guys are really improving. Thats special to us." Ryan went 8 for 15 and threw an 8-yard touchdown pass to Julio Jones. "We were better this week than we were last, and thats what you want to do in the preseason, you want to continue to get better," Ryan said. "Again, weve got a long way to go, but it was a good start." Steven Jackson had 42 yards rushing on eight carries against a defensive unit that has seven new starters. "Having success tonight is great for our confidence," he said. "Weve been working on the chemistry between the running back and the offensive line, and we feel the hard work showed tonight." The Ravens, conversely, were embarrassed by the easy fashion in which the Falcons moved downfield. "That was not us," Ravens defensive co-ordinator Dean Pees said at halftime. "Thats not how we play. Our fundamentals were not what they should be." Baltimores offence wasnt much better. Ravens quarterback Joe Flacco played the first halff, completing 7 of 9 passes 118 yards, including a 77-yard touchdown pass to Torrey Smith.dddddddddddd But over the first 30 minutes, the Ravens got only 54 yards on 18 plays besides the pass to Smith. "That first half was about as poorly as we can play," sixth-year coach John Harbaugh said. "I cant remember us playing worse since we came here." Atlanta had its way with Baltimores defence, even though receiver Roddy White hurt his ankle in the first quarter and did not return. "We made the decision that Roddy was not going to come back in the ballgame," Smith said, refusing to address the particulars of the injury. After going three and out on the opening series, Flacco put the Ravens up 7-3 with a touchdown pass to Smith, who cut across the middle of the field from the right side and outran Asante Samuel to the end zone. Atlanta bounced right back, moving 80 yards in seven plays to take a 10-7 lead. Jones burned cornerback Jimmy Smith for three catches totalling 55 yards, including an 8-yard touchdown play. In the first quarter, the Falcons ran 21 plays compared to seven for Baltimore and built a 10-1 advantage in first downs. "We were just sloppy. We never got into a rhythm," Flacco said. "The one drive we did score on, it was just one play." A field goal by Jeremy Shelley and a 2-yard run by Jacquizz Rodgers made it 20-7. Last season, the Ravens held opponents under 20 points in nine games (including two in the playoffs). In their preseason opener, they hammered Tampa Bay 44-16. This game was decidedly different. "This was good for us. A little humble pie," linebacker Terrell Suggs said. "We had a lot of success last week, with everything pretty much going our way. Atlanta is a very good team, and you cant make the mistakes we did. Its that simple." Guard Jah Reid said, "Well learn from it, well watch film from it and well get better from it."
