Michael Weiner, assistant general counsel of the Major League Players Assn., said Tuesday that the union will decide "in the next few days" whether to file a grievance on behalf ofOtis Nixon.
The Atlanta Brave outfielder was suspended for 60 days by Commissioner Fay Vincent Monday after a positive drug test, a violation of his 1987 aftercare program.
A grievance, Weiner said, could be based on any one of several aspects.
"We could challenge the accuracy of the test and the severity of the discipline," he said. "We have had discussions and negotiations with the commissioner in the past on his 60-day penalty for a second offense.
"We could also question whether Nixon was actually a second-time offender. His program was instated when he was a minor leaguer. We knew nothing about it."
