NEW YORK -- Nick Monroe went tumbling over the wall and suddenly realized it was a long way down, the world moving in slow motion as he fell head first toward the concrete floor.The American doubles player was crumpled on the ground for more than five minutes during Sundays U.S. Open match, too dizzy to stand up. He was eventually able to walk back on court under his own power, and after passing a concussion test, he returned to finish out the last three games.In the third set of his match with Donald Young on the new Grandstand, Monroe chased after a volley hit at a sharp angle and slid into a knee-high barrier along the side of the court. He flipped over the wall, and on the other side, the base of the stands is lower than the court.Just saw the ball and ran for it, he said, and didnt realize the wall was there.Monroe added he was fairly certain he never lost consciousness and was aware of the score and the situation the whole time. Young climbed over the barrier to check on him and Monroe could hear what he was saying, but he was too dizzy to move for a couple of minutes.Their opponents, Spains Pablo Carreno Busta and Guillermo Garcia-Lopez, also came over to see if he was OK as medical staff attended to Monroe. He was then taken inside for close to 10 minutes for concussion tests as Young sat in his changeover chair and the Spaniards hit the ball back and forth to each other on court to stay warm.The 34-year-old Monroe said he was put through a series of balance tests and asked to recite the months and the days of the week backward, and he passed everything.The teams had split the first two sets and the Americans trailed 4-2 in the third when the incident happened. Monroe held in his next service game, but the Spaniards closed out the 4-6, 7-6 (4), 6-3 victory to reach the quarterfinals.Monroe said about an hour after the match that he was still a bit dizzy and medical staff wanted him to come back to the tennis center over the next few days to continue to check on him. Hes never had a concussion before.I guess in tennis you dont really hit your head anywhere, he said with a chuckle.Monroe called the accident just a freak thing.Youre just so in the moment, he said. You want to win that bad, and you see the ball and you just go get it. Discount Hydro Flask . Team physician Dr. Steve Traina performed the surgery Friday.

CHARLOTTE, N.C. -- While Leonard Johnson may not be able to save Carolinas struggling secondary on his own, the veteran nickel cornerback has brought some needed energy -- and some playmaking ability -- to a group still looking for an identity after losing All-Pro Josh Norman to free agency this past offseason.Johnson was stellar in his first game with the Panthers last Sunday with eight tackles, a sack and pass breakup in 30-20 win over the Arizona Cardinals.But it was his all-in emotional intensity that teammates said made the biggest impact.He brought electricity, said defensive tackle Kawann Short.Teammates noticed Johnsons upbeat personality when he joined the team for training camp -- even though he was rehabbing on the side with trainers.Panthers general manager Dave Gettleman thought enough of the 5-foot-10 Johnson to sign him as a free agent in July even though he was still working back from a torn Achilles. During rehab, Johnson would wear game pants -- rather than just athletic shorts -- to practice, a reminder to himself of his desire to get back on the field.Hes hungry -- and I like that, Panthers defensive coordinator Sean McDermott said.Johnson stepped into a secondary that had allowed Matt Ryan and Drew Brees to throw for a combined 968 yards and eight touchdowns in two of the three previous games.It didnt take long for Johnson to make an impact Sunday.I noticed it right away, Rivera said. I was like, `OK, hes getting into it. And he was into it. And he was definitely chatty. You could hear him out there. He says some pretty outlandish things in terms of getting after guys and challenging guys. He does bring that energy.Sometimes too much energy.Johnson would have had two sacks on Sunday had he not been flagged for unnecessary roughness when he ripped the quarterbaack Carson Palmers helmet from his head.dddddddddddd That cost the Panthers 15 yards -- and Johnson a $9,175 fine from the league for an illegal hit.He apologized to his teammates at the time, but they simply told him to keep playing hard and bring the energy.He did just that.He brought juice, linebacker Luke Kuechly said. Leonard has love for the game and thats good to have.Added safety Kurt Coleman: Whether he was trying to make a play or trying to hustle to the play, he was full out. Was he perfect? No. But he made a lot of things happen. It was just a great addition to what we strive to be, a team that is running to the ball to make things happen.Rivera said the Panthers have been looking for a slot cornerback similar to Captain Munnerlyn, who left to join the Minnesota Vikings as an unrestricted free agent following the 2013 season.They think they have finally found that replacement in Johnson. Hell get another shot Sunday on the road vs. the Rams.Its only been one game, but hes done some really good things, Rivera said. You can also tell he was rusty. We just feel if we continue to grow and things get better, he can be a big part of what we want to do on defense.Game notes Left tackle Michael Oher (concussion), center Ryan Kalil (shoulder), linebacker Shaq Thompson (knee), cornerback Daryl Worley (elbow) and defensive tackle Vernon Butler (ankle) did not practice Thursday and their status is uncertain for Sundays game against the Rams is uncertain. Kuechly was held out of practice as a precautionary measure with a groin injury, but Rivera said he should be back to work on Friday.---AP NFL website: http://pro32.ap.org and http://twitter.com/AP-NFL ' ' '
