Kikuchi (shoulder) will be shut down from throwing for 3-to-4 weeks, Alden Gonzalez of ESPN.com reports.
The fact that the 34-year-old southpaw doesn't seem to need surgery makes it more likely that he returns before the end of the season, but it could still be a while before he appears on a big-league mound. The Angels plan to build Kikuchi up as a starter once he's cleared to begin a throwing program, and they may have a better picture of his return timeline once he progresses to that point.
