Along with the rest of the NFL, the Detroit Lions must reduce their roster to 75 players by Tuesday. They'll play their preseason finale Thursday at the Buffalo Bills and then cut their roster again to 53 players by Saturday. On the cusp of a busy week, both in the NFL and here on ESPN.com, let's review some of the biggest personnel issues the Lions have been working through this summer:
Right tackle/right guard
Seifert comment: Jason Fox started at right tackle and rookie Larry Warford at right guard in the presumably pivotal third preseason game, and that's the combination many of us thought would ultimately emerge from this competition. But the Lions haven't announced any winners, and coach Jim Schwartz said: "We have a lot of different options and a lot of guys that can potentially get the job done."
No. 2 receiver
Seifert comment: As we noted over the weekend, the Lions reportedly are making calls to see if they can upgrade here. That's understandable. Nate Burleson and Ryan Broyles are both working in the slot position. Patrick Edwards hasn't done much in the preseason after being given a nice opportunity to earn the role. Journeyman Matt Willis has been more productive. Chaz Schilens and Mike Thomas have already been released.
Seifert comment: The Lions started off veteran Ashlee Palmer in this role and he has not relinquished it. Second-year players Tahir Whitehead and Travis Lewis have not mounted a serious challenge, and defensive coordinator Gunther Cunningham has suggested Lewis might be better suited in the middle. Two recent veteran acquisitions, Rocky McIntosh and Chris White, seem targeted more for special teams roles.
Seifert comment: So far, it appears that the Lions' limited plan for Louis Delmas' camp participation has worked. Delmas looked healthy and active in 12 preseason snaps last week, and barring a flare-up of his knee condition, he is expected to start in Week 1 against the Minnesota Vikings.
Seifert comment: Rookie Darius Slay had some predictably tough moments last week against Tom Brady, but there doesn't seem to be much reason to go back to veteran Ron Bartell. If anything, newly-signed Rashean Mathis will push for playing time, perhaps at nickel in competition with Bill Bentley.
Seifert comment: The Lions have gotten returns from five different players in preseason games. They're trying to decide whether to dedicate a roster spot for a returner or use a backup player to handle the job. To this point, none of the participants
Seifert comment: Once David Akers proved he was healthy, it was clear the job would be his. Havard Rugland has been a fun camp story, but it's hard to imagine the Lions finding a spot on their roster for him -- especially with punter Sam Martin kicking off. Akers has converted seven of eight field goals in the preseason.
