Phillies infield prospect Aidan Miller is expected to be sidelined for roughly two additional months after undergoing a back procedure, according to reports from multiple outlets. The Athletic says Miller is set to undergo a radiofrequency ablation focused on the facet joints, a treatment the Phillies describe as “minimally invasive.” The New York Post similarly reports that the organization’s top prospect will be kept out longer than initially planned and frames the setback as extending his time away from the field by about two months.

Both reports indicate Miller’s injury issue is in his back and that the team is using a medical intervention aimed at reducing the underlying problem associated with that pain. While the exact timeline to return can vary based on how he responds to treatment and follow-up care, the shared expectation across the reports is that he will not return to play immediately and will likely remain out for the next couple of months.
