The award, which is given to the nation's best player, is usually handed out to the top offensive player of the year. Last year, Notre Dame linebacker Manti Te'o earned the honor, the first time since 1998 a defensive player had received the award.
Martinez and Abdullah were two of only six players from the Big Ten making an appearance on the list out of 50 total.
Martinez already holds the school record for career total-offense. The senior has thrown for 6,591 career passing yards – also a Nebraska school record. He's thrown more touchdowns than any quarterback to wear a Nebraska jersey, earning freshman All-American honors and first-team All-Conference honors last year.
Abdullah, who was thrown into the starting lineup last season after Rex Burkhead's knee injury, rushed for 1,137 yards and eight touchdowns as a sophomore and helped Nebraska lead the Big Ten and rank eighth nationally in rushing offense. His play earned him second-team All-Big Ten honors.
The last player to win the Walter Camp award for Nebraska was Eric Crouch in 2001. In total, three players have won the award since 1972.
