As petrolff1107 noted, lingering issues from a neck injury in 2011 have forced popular S Dietrich Riley, of La Canada, to take a medical retirement. Unfortunately, Riley's retirement leaves only Randall Goforth, as a returning starter, as Andrew Abbott, Aaron Hester and Sheldon Price have exhausted their eligibility and Tevin McDonald was dismissed from the team for violating team rules.
Some of you may remember Riley, as the highly touted defensive back recruit who was the target of a highly publicized Los Angeles recruiting battle. Riley ultimately spurned his childhood favorite team, Southern Cal on ESPNLA to play for then head coach, Rick Neuheisel and the UCLA Bruins. Optimism was high, as Neuheisel was able to secure a top recruiting class in 2010, and Riley was one of the more decorated recruits. While Riley's once promising career may not have ended like he had wished, we wish the hard-hitting safety nothing but the best in his future endeavors and like other highly touted prospects who were forced to medically retire before him (Wade Yandall, Chris Ward, Alex Mascarenas, Patrick Larimore, etc.), his future is bright, as a Bruin.
For all of you fans who were at the Oregon State game in 2010, I'm sure you remember the monster hit that then freshman Riley put on Jacquizz Rodgers. The pure impact of the hit knocked the helmet off of Rodgers despite the hit not being to the head, and put him in a stupefied daze.
