Chase Utley's rehab assignment appearance for Triple A Lehigh Valley on Tuesday is sold out. The remaining standing-room only tickets were purchased by midday Monday.
The IronPigs host the Rochester Red Wings at 7:05 at Coca-Cola Park in Allentown.
Utley, sidelined all season with knee issues, could be back in the Phillies lineup Wednesday, according to CSNPhilly.com.
In nine rehab games with Class A Clearwater, beginning June 12, Utley was 5-for-32 (.156) with one home run and five RBI. He played consecutive games at second base for the first time Friday and Saturday.
