Major League Baseball Players Association officials have discussed the possibility of Donald Fehr returning, according to sources.
The health of cancer-stricken union chief Michael Weiner has not improved.
Fehr, who led the baseball union for 26 years through collusion cases and labor battles ceded the union's executive director position to Weiner in 2009.
Fehr has neither discussed a return nor has any inclination to leave the NHLPA, according to sources.
