The Nationals placed Corbin on the bereavement list Friday, Jesse Dougherty of The Washington Post reports.
Corbin just pitched Wednesday against the Mariners and will presumably be back by his next scheduled turn in the rotation. The 33-year-old lefty has a 5-9 record with a 4.84 ERA, 1.54 WHIP and 66:29 K:BB in 96.2 innings (17 starts) this season.
