Doubs (undisclosed) remained sidelined at practice Thursday, Taylor Kyles of CLNSMedia.com reports.
Doubs also missed Wednesday's session with an undisclosed issue, so his status will be worth monitoring as the Patriots' Aug. 13 preseason opener against the Colts approaches. For now, consider the Patriots' No. 2 WR day-to-day until added context regarding his absence is provided.
