Morrissey is "stable" and has been discharged after spending the night in a hospital in Swindon, England. The singer, 50, collapsed on stage Saturday night while performing at the city's Oasis Leisure Centre.

Medics told reporters that he had been suffering from "respiratory problems" and was kept in the hospital over night as a "precautionary measure."

"He was seen this morning and was much improved and has now been discharged," Swindon's Great Western Hospital said in a statement.

Morrissey's 'Swords' tour, named for his forthcoming album of B-sides, kicked off Friday night in Birmingham.

According to a fan at last night's show, Morrissey "kept putting his hand up to his mouth as if he felt sick or ... perhaps he was trying to hide something, but he didn't look particularly comfortable," the fan told the BBC. Others described him as "straining" and "wincing," reports NME.

He collapsed in the middle of the first song, the 1983 Smiths hit "This Charming Man," and was led off stage by two of his band members.

Morrissey has canceled several tour dates this year due to illness. The U.K. leg of his tour, which includes several rescheduled dates from earlier this year, is set to resume Monday night with a performance in Bournemouth. The tour moves to Europe in November, followed by several U.S. dates.

The singer's website posted an update on his condition this morning, and did not suggest any forthcoming tour dates would be canceled. "Morrissey is in stable condition after his collapse in Swindon Saturday night," the site reads. "Thanks go out to all his well wishers, more information will be posted as soon as it is available."
