"The first thing he said was, 'Mom, calm down, I'm OK,'" she said.
Ware intends to return the court.
The broken leg, held together by two metal plates, will heal in eight to 12 weeks, he said.
"I will play basketball again," Ware said. "I know patience is key."
Team rallies around him
Earlier Wednesday, Ware recounted at a news conference his distress the moment his leg broke and immediate support from his teammates.
He said he was surprised to see some of them crying.
"Everybody was in real shock, and just looking around and seeing that, it was devastating," said Ware, who was using crutches Wednesday.
"But they pulled it through, and that's really most important right now," Ware said.
The injured player looked down at his body. It changed his state of mind.
"I see my bone is 6 inches out of my leg, and I go into automatic shock," he told reporters at a news conference. His foot was dangling off of his shin like a limp rag.
Faith and inspiration
Teammate Luke Hancock came over to Ware as he lay on the floor and said a prayer for him.
Ware said to himself that "I'm either going to cry ... or I'm just going to try to say some words (to help the team)." He thought of his team and put the pain behind him.
In a two-hour surgery, Ware's broken tibia was straightened and a rod was inserted into it, according to a statement from Kenneth Klein, senior associate athletic director for media relations at the university.
For the team and victory
In spite of the pain and the road to recovery ahead, Ware is still thinking of his team, not himself.
"I'll be fine, but (we've) still got to win this championship," he said.
Mr. Inspiration is ready for the Final Four, where his team is two games away from a potential national championship.
He has already made his way to Atlanta to cheer the Cardinals on in person. During his interview with CNN, he and his mother donned T-shirts with the words "Win it for Kevin."
Louisville takes on Wichita State at 6:05 p.m. ET Saturday, with the winner advancing to the national championship game Monday.
