Robinson's assistant, Diane Hock, told The Associated Press that the 16-time Gold Glove Award winner is "home and doing well."
Robinson, who played third base and spent his entire 23-year Major League career with the Orioles from 1955-77, was hospitalized for two weeks at Greater Baltimore Medical Center in April before undergoing what was expected to be routine surgery. He returned to the hospital last week.
"As you may recall, I was hospitalized in April for a routine procedure," the 18-time All-Star said in a statement released on Saturday. "I was recently hospitalized for a follow-up procedure, also routine, and am expecting that I will undergo two additional procedures over the next several months that will provide me with a complete recovery from a prior abdominal surgery.
"These are routine and expected procedures, and I continue to remain cancer-free," said the 1964 American League MVP Award winner, who was treated for prostate cancer in 2009.
Robinson was unable to attend a news conference last week to introduce the rosters for the 30th annual Brooks Robinson High School All-Star Game. The game, which features the best players from each region of Maryland, was played at Camden Yards on Sunday following Baltimore's 9-6 loss to Tampa Bay.
"Brooks wants to be here," third baseman K.J. Hockaday, whom the Orioles drafted in the 14th round of the 2011 First-Year Player Draft, told the Baltimore Sun. "We're just praying he gets better."
