Edward Aschoff, an ESPN college football reporter known for his lively blog posts and thoughtfully reported features, died on Tuesday after a brief illness, the network reported. It was his 34th birthday.

Mr. Aschoff had contracted pneumonia about a month ago, according to his social media posts. “I had a virus for two weeks. Fever and cough and the doctors think it turned into this multifocal pneumonia recently,” he tweeted on Dec. 5, noting that he rarely gets sick and had been taking antibiotics.

Mr. Aschoff was planning to marry his fiancée, Katy Berteau, in New Orleans in April.

On Thursday night, Ms. Berteau posted several times from Mr. Aschoff’s Twitter account, saying that her fiancé would have wanted people to have accurate information about his grave respiratory illness.

“Edward was admitted to the hospital a week after our first visit to the ER, where he was diagnosed with multifocal pneumonia,” Ms. Berteau wrote. “After failed antibiotic treatment, with worsening of symptoms, we took him back to the ER and he was immediately admitted.”
