Davis signed a one-year deal with the Lions on Friday, Justin Rogers of The Detroit News reports.
Davis spent his first four seasons in the NFL with the Lions before signing a one-year, $5.5 million contract with the Jets ahead of the 2021 campaign. However, he failed to live up to the deal, as an ankle injury sidelined him for the first six weeks of the season. Back with Detroit, he isn't guaranteed a significant defensive role, but Davis' past efforts have drawn the attention of head coach Dan Campbell, and he'll definitely have an opportunity to compete for a sizable role during training camp.
