Backup RB returns

The Arizona Cardinals have re-signed nine-year NFL veteran Chris Johnson, 31, to a one-year contract. he is expected to provide backup support for All-Pro David Johnson at the position. Chris Johnson spent the last two seasons with Arizona. He played in only four games last season before a groin injury sidelined him for the rest of the year. He led the Cardinals in rushing in 2015 with 814 yards on 196 carries, an average of 4.2 yards per attempt, but his playing time diminished with the emergence of rookie David Johnson.
