Christopher Duan "Chris" Johnson (born September 23, 1985) is a former American football running back.
Born in Orlando, Florida, Johnson emerged as a senior for East Carolina University where he broke out for 2,960 all-purpose yards and 24 touchdowns.
He was drafted by the Tennessee Titans in the first round of the 2008 NFL Draft, after running a then-record breaking 4.24 seconds in the 40-yard dash at the NFL Combine.
In 2009, he won the NFL rushing title with 2,006 yards (the sixth of only seven players ever to gain over 2,000 in a season), and broke Marshall Faulk's record of total yards from scrimmage with 2,509.
This earned him the nickname CJ2K.
He has been to three Pro Bowls and was the NFL's Offensive Player of the Year in 2009.
