Doping

FILE - In this Oct. 7, 2001, file photo, San Francisco Giants' Barry Bonds smiles as he begins to round the bases after he hit his 73rd home run of the season, against the Los Angeles Dodgers in a baseball game in San Francisco. The baseball Hall of Fame won’t have any new players in the class of 2021 after voters decided no one had the merits — on-the-field or off — for enshrinement in Cooperstown on this year's ballot. Curt Schilling, Bonds and Roger Clemens were the closest in voting by members of the Baseball Writers' Association of America released Tuesday, and the trio will have one more chance at election next year. It's the first time the BBWAA didn't choose anyone since 2013. (AP Photo/Eric Risberg, File)

FILE - In this Oct. 25, 2007, file photo, Boston Red Sox's Curt Schilling pitches against the Colorado Rockies in Game 2 of the baseball World Series at Fenway Park in Boston. Like many baseball writers, C. Trent Rosecrans viewed the Hall of Fame vote as a labor of love. The results of the 2021 vote will be announced Tuesday, Jan. 26, 2021, and Rosecrans was not alone in finding the task particularly agonizing this time around. With Schilling's candidacy now front and center — and Barry Bonds and Roger Clemens still on the ballot as well — voters have had to consider how much a player’s off-field behavior should affect his Hall of Fame chances.

The UFC will no longer punish fighters for using marijuana in most cases, making a major change to its anti-doping policy. The world’s largest mixed martial arts promotion won’t allow fighters to compete while under the influence of cannabinoids, but the promotion recognizes that MMA fighters often use marijuana for pain management or relaxation. Diaz is among many fighters who already used marijuana actively when not in competition. (AP Photo/Gregory Payan)
