The United States Anti-Doping Agency (USADA) is investigating Nate Diazs open use of a vape pen shortly after his riveting five-round fight against Conor McGregor at UFC 202.I can confirm that USADA is aware of the situation and is currently gathering information in order to determine the appropriate next steps, said USADA spokesperson Ryan Madden.During Saturdays postfight press conference, Diaz, who suffered a majority decision loss to McGregor at T-Mobile Arena in Las Vegas, openly vaped while answering media questions.When asked what substance the pen contained, Diaz, 31, said it was CBD oil -- otherwise known as cannabidiol. Cannabidiol is considered a banned substance in-competition, under the classification of cannabinoids.CBD oil, Diaz said when asked about the vape. It helps with the healing process and inflammation, stuff like that. You want to get these before and after a fight, training. Itll make your life a better place.The in-competition window extends to six hours after a UFC fight. Diaz submitted a fight-night drug test prior to the news conference, the results of which were not yet available. The threshold for marijuana metabolites under the UFC program, as well as statutes of the Nevada State Athletic Commission, is 150 nanograms per milliliter (ng/mL).The USADA could argue Diazs admission of using CBD oil within a six-hour time frame is a violation of the UFCs anti-doping policy. If the USADA were to rule a violation has occurred, Diaz could face up to a one-year suspension.Diazs representatives were not immediately available for comment.Diaz (19-11) has never failed a drug test. His older brother, UFC welterweight Nick Diaz, recently completed an 18-month suspension for his third marijuana-related offense. Nate Diaz, who fights out of Stockton, California, already has called for a trilogy fight against McGregor. Stitched Jerseys .

He totaled 41 tackles and three interceptions while starting all but four of the 13 games he played last season. The Kerala Cricket Association has issued a show-cause notice to Sanju Samson for alleged acts of indiscipline during the ongoing Ranji Trophy season, and has appointed a four-member committee to look into the allegations. Samson has subsequently been dropped for Keralas ongoing match against Tripura in Cuttack for disciplinary reasons.KCA secretary TN Ananthanarayanan alleged Samson had misbehaved on several instances during the season. He is also said to have left the Brabourne Stadium in Mumbai without informing the team management while the game against Goa was in progress.After he was out for 0 in the second innings, he returned and broke his bat in the dressing room, Ananthanarayanan told ESPNcricinfo. He then went out without informing anybody in the middle of the match and came back only at 8 or 9 pm. We didnt tell BCCI or anybody else regarding this because he is an upcoming player and we want to encourage him. But, he hasnt been co-operating with the team management.According to Ananthanarayanan, Samson had complained of a knee injury ahead of the Tripura game and wanted to go to the National Cricket Academy in Bangalore for rehabilitation. He said prevailing fitness issues within the squad - Akshay Chandran, Akshay KC and Jalaj Saxena were all injured and their availability for the eighth round was uncertain - played a hand in KCA not releasing him from the squad.Soon after he was dropped, Samsons father, Vishwanadh Samson, came to Cuttack and insisted on takiing his son back to Trivandrum.dddddddddddd, Ananthanarayanan said. Sanjus father called our president [TC Mathew] and used bad language against him. However, according to a Times of India report, Vishwanadh Samson admitted to speaking to Mathew, but denied abusing him.There is no truth in the allegation. Why should I abuse the KCA president who has worked tirelessly for the betterment of the game, he asked. I wont play with my childs future. I dont know from where such baseless stories emanate. ESPNcricinfos attempts to contact Sanju, Samson and KCA president Mathew remained unsuccessful.Ananthanarayanan said the inquiry committee will likely hear the matter by the middle of December. [KCA vice-president] TR Balakrishnan is the chairman of the committee, which comprises Sreejith V Nair, S Ramesh and P Ranganathan, he said. The committee has to decide by when Samson should respond to the show-cause.Samson started the season with 154 and 47 in Keralas first two games, but has failed to get into double digits in four of his last five innings, which include two ducks. Prior to that, he was part of the India A squad that toured Australia in July-August. He scored 147 runs in five innings, including two fifties, in the 50-over quadrangular tournament. He then played the second unofficial Test against Australia A and managed 47 runs in two innings. ' ' '
