On Sunday, the Detroit Lions announced that they have placed a handful of players on the injury lists ahead of training camp. Cornerback Jerry Jacobs, defensive ends Romeo Okwara and Josh Pachal have all been placed on the physically unable to perform (PUP) list, while Jameson Williams and linebacker Natrez Patrick have been placed on the non-football injury list.
The NFI and PUP lists work essentially the same. Players placed on the preseason PUP/NFI list are eligible to come off of the list and participate in camp at any time during the preseason. If a player remains on the PUP/NFI list until the end of the preseason, teams have an option to place those players on the regular season PUP/NFI list, which means they would have to sit out the first four games of the season (in previous years, it was six games).
