(CNN) -

Republican officials on Sunday released a new schedule for this week's Republican National Convention in Tampa, Florida, one day after announcing the gathering would be postponed by a day due to weather conditions related to Tropical Storm Isaac.

Among the major changes: South Carolina Gov. Nikki Haley's speech has moved to Tuesday night, former Arkansas Gov. Mike Huckabee speaks on Wednesday night and former Florida Gov. Jeb Bush delivers his remarks Thursday night.

The primetime hour of 10 p.m. ET did not undergo any changes, officials said on a conference call with reporters.

"There have been a few speakers who weren't headliners that we had to let go," Romney for President Strategist Russ Schriefer said on the call.

Earlier Sunday, GOP officials signaled they were considering an extension to the convention by holding events on Friday, but the new schedule does not include any events for that day.

"We are not considering a Friday session," convention organizers told reporters. "However, we have a weather event. We'll watch the weather and if because of the weather something has to change, we'll let you know."
