Los Angeles Chargers defensive tackle Brandon Mebane revealed his daughter Makenna died on Jan. 3, according to ESPN.com's Eric Williams.
"I'm still thankful, and I thank God every day," Mebane said. "We're taking it one day at a time."
Mebane took a two-week break in December following Makenna's birth. He told Ricky Henne of the Chargers' official site that Makenna was born a month premature.
He also said an ultrasound in July showed Makenna had trisomy 13, a heart defect.
