With the condition of cancer-stricken union chief Michael Weiner not improving, MLB Players Association officials have discussed the possibility of a return of his predecessor, NHLPA director Donald Fehr, sources told Yahoo! Sports.

Fehr, who led the baseball union for 26 years through collusion cases and labor battles, including the infamous 1994 strike, ceded the union's executive director position to Weiner in 2009. Whether Fehr would consider rejoining the union in a senior management role or as an adviser is unclear, and sources said Fehr has neither discussed a return nor has any inclination to leave the NHLPA. His name nevertheless surfaced as baseball union officials aim for the delicate balance between hatching a contingency plan and respecting Weiner's continued work on MLBPA business, sources said.
When reached by Yahoo! Sports, Fehr and the MLBPA declined comment.
Fehr is one of a number of names being considered by the union in case Weiner's health worsens. Less than a year ago, Weiner, 51, was diagnosed with an inoperable brain tumor. He is on his fourth round of cancer treatments.
Weiner plans on attending the Home Run Derby and All-Star Game at Citi Field on Monday and Tuesday, a source said.
