Bronny James is improving after suffering cardiac arrest Monday and his parents, LeBron and Savannah, are “relieved,” according to a TMZ report.

The report states the couple is “optimistic,” although more tests will be done in an attempt to determine the cause of the cardiac arrest.

Bronny, 18, is an incoming freshman at USC and suffered cardiac arrest Monday morning while practicing at the school’s Galen Center.

Medical staff treated Bronny and took him to Cedar Sinai Hospital in West Hollywood, and he was in stable condition and no longer in ICU as of Tuesday, according to a statement released by the James family.

“LeBron and Savannah wish to publicly send their deepest thanks and appreciation to the USC medical and athletic staff for their incredible work and dedication to the safety of their athletes,” the James family said in a statement to TMZ.

LeBron, who has stated he hopes to play with his son in the NBA before he retires, visited Bronny in the hospital Tuesday.

Sports stars and legends around the world have offered their support to Bronny and the James family, including Bills safety Damar Hamlin and ESPN’s Stephen A. Smith.

Hamlin tweeted he will be there for the family, like it was there for him after he suffered cardiac arrest in January.

Smith said he’s thankful Bronny is doing OK and praised both Bronny and the entire James family.

“If you know anything about LeBron James, you can say whatever you want, people can be critical, but nobody debates what a loving, wonderful father he is and how much he loves his children, especially Bronny,” Smith said on ESPN’s “First Take” on Tuesday.

“We see Bronny everywhere, we see him talking about Bronny all the time, his wonderful wife, Bronny’s mother, Savannah, first class all the way, a wonderful human being. They have a great, great family and Bronny has never done anything to besmirch or sully the James name.”

Bronny, a point guard, is ESPN.com’s No. 20 recruit and committed to the Trojans in May.

He chose USC over several elite programs, like Ohio State, Kentucky and Michigan.
