Norris was placed on the disabled list Tuesday, Pedro Moura of the Los Angeles Times reports.

EDGE Analysis

It's unclear what Norris is dealing with, or when the issue cropped up on him, but it could help explain his brutal run of form over the past month. Over his last 13 appearances (dating back to July 25), Norris has blown two saves and compiled an abysmal 12.66 ERA and 2.34 WHIP. A timetable for his return should come into focus once the Angels provide more details regarding his status. Eric Young was recalled from Triple-A Salt Lake to take his place on the roster.
