The contract of Titans running back Chris Johnson is expected to be an issue once the NFL league year resumes. The team was able to satisfy him by adding $1.5 million to his $500,000 base salary prior to the 2010 season, but he'll likely demand more this time around. Johnson, set to receive just $800,000 in 2011, is preparing for a much more prolonged holdout if need be and remains committed to joining the game's highest-paid running backs, according to sources.
