Smith (elbow) was activated from the 60-day disabled list Tuesday, Evan Drellich of CSN New England reports.
His return was delayed by a day after he was struck by a line drive in the leg in his final rehab start over the weekend. Seeing as Smith has only made three appearances for the big club since the start of 2016, he will likely be eased back into action in a lower-leverage role. The hope is that he'll be ready to contribute more substantially in 2018 after building his arm back up in the offseason. Kyle Martin was designated for assignment to clear room for Smith's return.
