Isiah Kiner-Falefa is due to begin a rehab assignment at Triple-A Worcester on Wednesday.
Kiner-Falefa, out with forearm inflammation, was moved to the 60-day IL earlier this week, but he’ll be eligible to return from that even before the rehab assignment starts. The Red Sox probably won’t rush to bring him back, as they also have Trevor Story returning and only so much room on the roster.
