Kozlowski, who wore number 7, was a standout wide receiver on BYU's 1984 National Championship Team; he was known for making clutch, acrobatic catches.
At the time, Glen was one of only two players (along with Todd Christensen) to start at BYU as a true freshman, playing with several standout quarterbacks over the course of his career: Jim McMahon, Steve Young and Robbie Bosco.
As a show of support for his injured teammate, BYU quarterback Robbie Bosco switched his jersey number from 6 to 7 for one game.
Although Kozlowski played well in his replacement role, he suffered a broken leg while returning a kickoff, ending his "spare Bear" season.
Glen married his college girlfriend, Julie, and all of Kozlowski's sons attended BYU with one, Tyler, playing football as a freshman walk-on.
