Curt Schilling says he has completed chemotherapy treatment and has radiation treatment ahead.
Schilling released a statement Feb. 5 saying he had cancer, and daughter Gabby tweeted the following week that he had undergone surgery.
The former pitched said in a Twitter posting Tuesday night: "Chemo done, 5 radiations remain."
He has not said what type of cancer he has or the prognosis.
A six-time All-Star who was 216-146 from 1988-07, Schilling won World Series titles with Arizona in 2001 and with Boston in 2004 and '07. He was hired in December to be part of ESPN's "Sunday Night Baseball" broadcast crew, and ESPN said Schilling will join the telecasts as soon as his health allows.
