Weaver (forearm) is throwing an extended bullpen before Sunday's game against the Pirates, Charlie Goldsmith of The Cincinnati Enquirer reports.

EDGE Analysis

If the bullpen goes well, Weaver is expected to begin a rehab assignment with Triple-A Louisville. The right-hander is on the injured list with soreness in his right forearm, and he has a chance to make starts for the Reds when he's able to return around the middle of April.
