News of the concussion, however, brings into focus a problem explored by front office personnel at the NFL scouting combine in 2014. Executives in personnel from four teams told the Journal Sentinel at the time about what they believed to be a history of concussions for Abbrederis.
Two scouts told the newspaper Abbrederis had suffered "three or four" concussions.
"I've heard it's three or four," a personnel director for an NFL team said at the combine in 2014. "I've got to find out the depth of it. I love him, but it makes me nervous."
At the time, Abbrederis insisted he had suffered just a single concussion in September of 2012 against Oregon State. "And it wasn't even a bad one," he said at the combine.
But Abberderis also suffered head injuries on two other occassions during his collegiate career: The first came against Penn State in November of 2012, and the second against Northwestern in October of 2013.
