According to Slater, Collins had been hoping to return this year, but his hip pain became intolerable.
Calvin Watkins confirms the news and adds that this is related to the hip injury he suffered during training camp and not related to the car accident he was involved in.
Collins was placed on injured reserve coming out of training camp.
Collins, 27, signed on with the Cowboys as an undrafted out of LSU in 2015. He was set to make a base salary of $616,750 for the 2017 season when the Cowboys signed him to a two-year, $15.4 million extension through 2019.
Collins is in the second year of his five-year, $50 million deal and is set to earn base salaries of $1,450,000 and $8,550,000 over the next two years.
In 2019, Collins appeared in 15 games for the Cowboys.
