Zack Martin is considering not reporting to camp with the Dallas Cowboys due to his unhappiness over his contract. Martin is scheduled to make about $7 million less this season than the NFL's top-paid guards. 

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

The Cowboys and Martin's representatives had brief discussions at the combine in February about reworking the seven-year, $93.41 million deal he signed in 2018, according to sources.
