TEMPE, Ariz. -- A blood test Thursday revealed that Arizona Cardinals wide receiver John Brown carries the sickle-cell trait and has been listed as doubtful for Sundays game, coach Bruce Arians said Friday.Brown experienced leg pain before Monday nights win over the New York Jets and was diagnosed with sore hamstrings after the game. But an MRI this week didnt reveal any issues with his hamstrings, which led to the blood test.Were investigating on how to help him get better as fast as possible, Arians said.According to the Centers for Disease Control and Prevention, sickle-cell trait is the result of one inherited sickle-cell gene and one normal gene. Those with the sickle-cell trait usually dont exhibit symptoms of sickle-cell disease. In rare cases, however, people with SCT might experience complications of SCD, such as pain crises.According to the CDCs website, those with sickle-cell trait are more likely to experience muscle breakdown when doing intense exercise than those who dont have the trait.Brown was plagued with hamstring issues for the last 2? months of last season, which Arians said is likely related to the sickle-cell trait diagnosis.Arians thinks Brown is relieved to discover a potential reason for this pain.I think hes very happy that he found out why his legs are hurting so bad, Arians said. NEW YORK -- The Tampa Bay Lightning are unhappy with a recent stretch of inconsistent play. The New York Islanders might be borderline ecstatic to have the Lightnings problems.A pair of teams feeling internal -- and in the case of the Islanders, external -- pressure to turn things around face off Monday night, when New York hosts the Lightning at Barclays Center.Both clubs are coming off losses on Saturday night. The Lightning fell to the San Jose Sharks, 3-1, while the Islanders blew a two-goal third period lead and lost to the Florida Panthers, 3-2, in overtime.The Lightning (8-6-1) have alternated wins with losses over the last six games (3-2-1), a stretch that comes on the heels of a four-game losing streak (0-4-0). Despite the up and down stretch, Tampa Bay is just two points behind third-place Ottawa in the Atlantic Division and tied with the Detroit Red Wings for the final wild card spot.We need to get some consistency in our game -- we havent seen that, we play good game, bad game, Lightning center Steven Stamkos said following Saturdays defeat. We just havent put any good ones in a row.The Islanders (5-7-3) are having the same issues, albeit on a more serious scale. New York has won consecutive games just once this season and has lost seven of its last 10 (3-4-3).The Islanders have either led or been tied in the third period in seven of their 10 losses. They gave up the game-tying goal with 13.6 secoonds remaining in regulation on Saturday night.dddddddddddd.With just 13 points this season, the Islanders are only one point ahead of the Carolina Hurricanes for last place in the Eastern Conference and in danger of falling out of the playoff race by Thanksgiving.Just got to focus on the positives right now, Islanders head coach Jack Capuano said following Saturdays defeat. When youre going through a stretch like this, the last thing you want to do is have negativity. Theres enough negativity around, so we just want to have a singular focus, continue to concentrate and hopefully the breaks will come.A pair of No. 1 goaltenders are likely to be in net. Ben Bishop has started three of the last four games for the Lightning and took the loss on Saturday. Bishop earned the win over the Islanders in Tampa Bay last Thursday, when he stopped 26 shots in a 4-1 victory that improved his career record against New York to 6-4-1.Islanders goalie Jaroslav Halak has cemented his standing by starting the last six games. He was pulled for backup Thomas Greiss in the second period Thursday, when he stopped just 13 of 16 shots. The loss dropped Halaks record against the Lightning to 4-3-0.The Lightning will be looking to sweep the season series from the Islanders, whom they also beat 6-1 on Nov. 1. ' ' '
