Portland State is mourning the sudden loss of linebacker AJ Schlatter, who died Sunday at home due to a complication from minor throat surgery.
The 20-year-old Schlatter's father Jim wrote a Facebook post Monday saying he believed his son developed a blood clot after having his tonsils removed Friday.
"He was such a inspiration to me and I was and am so PROUD to be his father," Jim Schlatter wrote.
Schlatter, a native of Canby, Oregon, was a redshirt freshman and starter for a Vikings squad that finished the season ranked No.
