Alexander exited Monday's game against the Angels early due to a muscle contusion, Andy Kostka of TheBanner.com reports.
Alexander's Monday night was cut short after fouling a ball off his knee which resulted in a knee contusion in the top of the second. When the 27-year-old was on the bench before going out for defense in the bottom of the third, he felt his knee lock up. Leody Taveras replaced Alexander at third base until he was moved to center field in the bottom of the eighth.
