Zach Martin did not report to the start of training camp with the Dallas Cowboys. Martin will incur a $50,000 fine for each day he misses.

Martin is unhappy with his current contract situation.

Martin said he is "woefully underpaid relative to the market," a source said.

Martin has two years left on his deal and is set to make $13.5 million this year and $13 million next year. Atlanta's Chris Lindstrom and Indianapolis' Quenton Nelson have the highest annual average salaries for guards at $20.5 million and $20 million respectively.
