Seager (back) is doing some light running on the field ahead of Friday's game against Atlanta, Evan Grant of The Dallas Morning News reports.
Seager has played just four games since June 11 due to concussion and back issues, and he's still recovering from lower-back inflammation. It's been an extremely disappointing season for the 32-year-old, who is slashing just .182/.292/.374 with 10 homers, 25 RBI, 28 runs scored, one stolen base and a 28:59 BB:K across 219 trips to the plate.
