Alex Rodriguez will be suspended Monday, likely through the end of the 2014 season, sources told "Outside the Lines" on Saturday.
About 12 other players will also be suspended Monday, according to sources.
Several sources familiar with the talks said tense deliberations between Rodriguez and commissioner Bud Selig's office broke down completely Saturday after Selig told officials he would no longer negotiate.
One source told OTL that MLBPA executive director Michael Weiner called MLB executive vice president Rob Manfred on Saturday asking for a meeting between the union, MLB, the Yankees and Rodriguez's camp, but MLB refused.
MLB has said repeatedly that the Yankees have no place in negotiations and that discipline was the domain of Selig and no one else, a source said. Several sources also said that Selig was "furious" with Rodriguez for telling reporters he would not negotiate, even as his attorneys sought a deal to mitigate MLB's looming punishment.
