After canceling his show Thursday night in Flint, Mich., Morrissey has been hospitalized.
The British rocker is reportedly "undergoing tests for a suspected bladder infection" at William Beaumont Hospital, his rep told Billboard.
In addition to Thursday's concert cancellation, Morrissey's concerts in Minneapolis and Chicago on Friday and Saturday were postponed.
Many of the former Smiths frontman's recent concert dates, including the Flint concert, were rescheduled tour dates from last year when he postponed the shows to spend time with his ailing mother.
Fans who purchased tickets in Flint were refunded their money, and those who purchased tickets for his shows in Minneapolis and Chicago were encouraged to hang on to their tickets to attend the concerts when they are rescheduled.
UPDATE: Morrissey's rep tells E! News that the singer has been diagnosed with a bleeding ulcer and is rescheduling his upcoming shows in Nashville; Atlanta; Asheville, N.C.; Lawrence, Kan.; Clear Lake, Iowa; and Lincoln, Neb.
"Morrissey is expected to make a full recovery and thanks everyone concerned for their support during this time," his rep says, adding that the tour will resume in Las Vegas on Feb. 9.
