McKinley agreed to a one-year deal with Dallas on Wednesday, Michael Gehlken of The Dallas Morning News reports.
McKinley was cut by the Rams in mid-October and signed a practice-squad deal with Dallas a month later. He didn't make any appearances for the Cowboys down the stretch, but he appears to have made enough of an impression in practices to get a chance to compete for a roster spot in 2023. The 2017 first-round pick recorded 16.5 sacks over his first three seasons in Atlanta, but he has just 3.5 across the past three campaigns.
