The Rays activated Lavender (elbow) from the 60-day injured list and designated him for assignment Thursday.
Lavender underwent surgery in late August or early September to remove a bone spur from his left elbow. It's possible he'll be available for the start of spring training. However, he'll be exposed to waivers after Thursday's move. Lavender, who turns 25 in January, has yet to make his MLB debut.
