Langford (hamstring) is expected to begin a minor-league rehab assignment as soon as Friday, Evan Grant of The Dallas Morning News reports.
The 22-year-old has been sidelined nearly three weeks by a strained hamstring but is in the latter stages of his rehab program. Assuming Langford is able to get in a couple games this weekend, he could rejoin the Rangers for an upcoming two-game series versus the Diamondbacks, which begins Tuesday.
