Ansah injured his shoulder and a biceps muscle in a December loss in Philadelphia and underwent surgery in February. He did not participate in any OTA or minicamp practices this spring.
He was the Lions’ sack leader last year as a rookie with eight and is expected to be an important playmaker up front for Teryl Austin’s defense in his second season.
Tate injured his shoulder in the spring and also sat out June’s mandatory minicamp. He told reporters he believed the injury to be minor at the time. He signed a five-year, $31 million contract this offseason as the team’s No. 1 free-agent target.
Jones, a sixth-round pick out of Notre Dame, underwent arthroscopic surgery in June to fix a shoulder injury he suffered in college and that lingered into the spring. He also didn't participate in June’s minicamp.
Players who start the year on PUP can come off the list at anytime during training camp and they still count toward the team’s 90-man roster.
Ansah, Tate and Jones are all expected to be ready for the start of the regular season.
