Weaver (hamstring) is expected to be placed on the 15-day injured list and could miss the next 4-to-6 weeks, Jeff Passan of ESPN.com reports.

EDGE Analysis

Weaver suffered the injury while warming up for Sunday's matchup against the Dodgers, and the injury appears to be more significant than initially thought after reviewing his MRI results. The team plans to disclose an official timetable for the closer's return Tuesday, per Passan. Weaver's absence will presumably mean more save opportunities for Devin Williams, who picked up his last save May 27 despite surrendering two runs on three hits against the Angels.
