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.
