Analysis: Cowser suffered structural damage to his thumb while he slid into first base during Sunday's 3-1 loss to the Blue Jays. The Orioles recalled Dylan Carlson from Triple-A Norfolk to provide extra coverage in the outfield while Cowser is out, but Heston Kjerstad appears to be the most likely candidate to earn regular playing time -- at least against right-handed pitching -- over the next several weeks. Hyde didn't say whether or not Cowser would require surgery on his thumb.
