Kansas City Chiefs running back Jamaal Charles does not plan to attend the opening day of training camp on Thursday and intends to hold out for more money, Kansas City, Mo., TV station KCTV5 reported Tuesday.
Charles, 28, rushed for 1,287 yards in 2013, which was the third best total in the NFL last season, and he ran for 1,509 yards in 2012.
However, 10 other NFL running backs have a higher base salary than Charles.
Charles has two more years left on his six-year contract and is due to make $3.9 million this year, according to ProFootballTalk.com.
A source told the TV station that Charles is prepared to sit out as long as it takes to get the contract he thinks he deserves.
He makes about $9 million per season less than Minnesota Vikings star Adrian Peterson. Detroit's Reggie Bush and Baltimore's Ray Rice also make more money than Charles.
The Chiefs said they expect Charles to show up on Wednesday when veterans report.
