Marcum, 29, is leaving the club to be with his father, who is having heart surgery.
The team has called up right-handed reliever Mike McClendon from Triple-A Nashville to take his place on the roster. McClendon has appeared in three games for the Sounds, allowing four hits and no runs in 6 1/3 innings. He's struck out four and walked one.
Marcum started on Monday, so he could easily return by Sunday, which would be his next turn in the rotation with Thursday's off day for the Brewers. Marcum allowed five hits and an unearned run in a no-decision in Milwaukee's 12-inning victory over the Phillies.
Players on the bereavement list must miss a minimum of three games and a maximum of seven.For more baseball news, rumors and analysis, follow @cbssportsmlb on Twitter or subscribe to the RSS feed.
