Second-round pick Josh Pachal underwent sports hernia surgery this offseason, Detroit Lions coach Dan Campbell said Wednesday on Day 1 of training camp.
Paschal was one of three players the Lions placed on the physically unable to perform list over the weekend.
A defensive lineman from Kentucky who is expected to have a rotational role this fall, Paschal took part in rookie minicamp in May but was a nonparticipant in practices open to the media the rest of the spring.
Campbell did not put a timetable on his return.
"He’s doing well, but it’ll be a little bit," Campbell said.
