Beck is scheduled to undergo vascular surgery Monday to address the aneurysm in his upper right arm, Andrew Baggarly of The Athletic reports.
The 27-year-old was diagnosed with the aneurysm Thursday after experiencing hand discomfort earlier in the week, and there won't be much of a delay before he goes in for surgery. Beck has already been ruled out for Opening Day, and a return timeline won't be established until after the procedure.
