Husain Abdullah has retired from the NFL, citing his health as the primary deciding factor. 

Abdullah suffered five concussions in his seven-year career.

Abdullah thanked the Minnesota Vikings for signing him as an undrafted free agent in 2008 and called his three seasons with the Kansas City Chiefs "the most enjoyable football experience in my entire life."

Kansas City used Abdullah, a part-­time starter over his three seasons, in a variety of roles.
