Houck (back) didn't throw live batting practice as scheduled Tuesday due to continued back soreness, Pete Abraham of The Boston Globe reports.

EDGE Analysis

The 26-year-old landed on the shelf Aug. 9 with a disc issue in his back and returned to throwing last week, but the ongoing soreness will prevent him from further ramping up his throwing program. Houck is already eligible to return from the 15-day IL, but he may still be a couple weeks away from rejoining the active roster.
