When that will be is still unknown because DeRosa's left oblique is still sore. The doctors want him to rest until the soreness goes away.
DeRosa is currently in New Jersey with his father, Jack, who is battling cancer. According to Johnson, Jack suffered a relapse recently.
"Mark is by his father's side right now. So we text back and forth. I told him [Jack] needs you more than we do. It's a good time to give [that oblique] a rest," Johnson said.
