Allen Park — The Detroit Lions' top free-agent addition will begin training camp on the physically unable to perform list.
The team announced Monday that defensive end Trey Flowers still isn't medically cleared, presumably from the offseason shoulder surgery that kept him sidelined during the early portions of the offseason program.
In addition to Flowers, linebacker Steve Longa was also placed on PUP list. Longa is still working his way back from last year's ACL injury.
