"He is still in [the] hospital in ICU so we are taking it day by day as he gets tested and recovers," the rep said.
Earlier on Thursday, Us Weekly reported that Bret could resume his tour by the end of May.
On his Web site, the star is still listed for a number of dates, including one as soon as May 7 in Wichita, Kansas, though on his MySpace, dates through May 21 are listed as being postponed.
The rocker-turned-reality star remains scheduled for a June and July tour with Lynyrd Skynyrd.
The star suffered a massive brain hemorrhage last week, just weeks after an emergency appendectomy. On Tuesday, his official site noted he had suffered a minor setback, due to a lack of sodium in his body.
