Iwakuma (shoulder) has been recalled from his rehab assignment at Triple-A Tacoma in order to undergo further medical evaluation, Bob Dutton of The News Tribune reports.

EDGE Analysis

It had already been announced earlier this week that the veteran right-hander's planned activation this coming Saturday had been scrapped, and Thursday's development paints an even murkier picture with respect to a potential return date. Iwakuma last big-league game action came on May 3, and he endured a rough two-inning outing in his rehab start for the Rainiers this past Monday.
