McCullers (elbow) will not throw for another week, Brian McTaggart of MLB.com reports.
Now close to two weeks into his DL stay, McCullers remains shut down from throwing and it will be another week before he even picks up a baseball. From there, McCullers will need to gradually ramp up his throwing, ultimately facing live hitters before heading out on a rehab assignment. It seems safe to assume at this point that he won't be back until after rosters expand.
