Keuchel will be shut down for a week to allow the discomfort in his neck to subside but there is a chance he'll only miss 1-to-2 starts, Richard Justice of MLB.com reports.
It appears that the Astros will exercise extra caution with their ace during his DL stint and make sure his neck is fully healed before letting Keuchel resume throwing. Assuming everything goes according to plan, Keuchel should be able to pick up a ball at some point next weekend, at which point there figures to be a firmer timetable for his return. Keuchel's absence leaves a major hole in the Astros rotation, but the club should be getting some reinforcements in the near future with Joe Musgrove and Charlie Morton nearing returns.
