Former Boston Red Sox closer Jonathan Papelbon, who was with the team from 2005-11, said Saturday that he and numerous other Red Sox players were regularly injected with Toradol, a legal anti-inflammatory drug whose use has become increasingly controversial in sports. Toradol is the nonsteroidal drug that Red Sox pitcher Clay Buchholz acknowledged last season might have contributed to the esophagitis that sidelined him for 20 games. Buchholz was hospitalized in intensive care and lost three or four pints of blood while dealing with the condition, which is a known side effect of the painkiller. Papelbon said that when he was administered a physical by the Philadelphia Phillies prior to signing as a free agent after the 2011 season, doctors asked him if he used Toradol. When he answered in the affirmative, he was told that he would have to stop.
