The Facts: The Lions have placed Harrison on the Reserve/Non-Football Illness list to make room on their 90-man roster for safety Sam Proctor and receiver Wallace Miles, whom the team signed after their tryouts at this weekend's rookie mini-camp. The Lions had to declare that Harrison would not be eligible to participate in the 2012 regular season or postseason for him not to count toward the 90-man roster while on the Reserve/Non-Football Illness list.

Diehards Line:Eagles doctors discovered a brain tumor in Harrison that nullified a trade that would have sent him and an undisclosed draft pick to the Eagles for running back Ronnie Brown last season. The trade might have actually saved Harrison's life. He's currently recovering from surgery to remove the tumor and is "progressing" according to his agent Mitch Frankel. Harrison signed with the Lions as an unrestricted free agent before last season after playing his first five seasons in the NFL with the Browns and Eagles.
