Addison Russell's administrative leave has been extended by Major League Baseball through Sunday.

Russell, 24, was placed on paid leave last Friday after his ex-wife posted a blog detailing abuse during their short marriage. She had not been cooperating in baseball's investigation, which was opened last season, but she is now opening up.

Under the collective bargaining agreement, a player can be put on paid administrative leave for seven days, which can be extended for up to another week. In this case, the leave coincides with the end of the regular season.

Russell could then be suspended or allowed to return to the Chicago Cubs, who have clinched a playoff berth.

"Domestic violence is horrible," Joe Maddon said. "It absolutely is. By reading that, you feel her pain, absolutely. ... But I don't know enough about the other side. I'm waiting for the full report to come out then we all can draw a conclusion."
