World welterweight champion Manny Pacquiao was admitted to a hospital to treat a mild stomach ulcer and allow him to rest after campaigning for the May 10 congressional elections. Pacquiao's chief of staff, Jayke Joson, said Monday that doctors discovered the 31-year-old boxer had an ulcer during a routine checkup Sunday and his family convinced him to stay in a suburban Manila hospital for a few days. "Really, Manny can only rest if you confine him to a hospital," Joson told The Associated Press, adding Pacquiao was receiving intravenous dextrose drips. "It's been so intense a campaign, he missed some of his meals." http://sports.espn.go.com/sports/boxing/news/story?id=5213931
