Rookie Brandon Hepburn, a seventh-round selection in April's draft, also is in camp. The focus for him and the other relative newcomers has been the same.
"Throughout camp we've been working them in for (first-team) reps," Palmer said. "We're just trying to get those guys the reps they need and help them see the plays they need to see.
"It's a good responsibility."
The Lions host New England on Thursday for the third exhibition game and open regular-season play Sept. 8 against visiting Minnesota.
Notes: Schwartz said it's too early to tell if receiver Calvin Johnson (knee), backup quarterback Shaun Hill and safety Louis Delmas (knee) will play Thursday night. "Today would be like a Friday in the regular season," the coach said. "A lot of those decisions we don't make until Saturday night before the game. We still have some time." . Detroit Tigers pitcher Max Scherzer, who earned his MLB-best 18th win Sunday, and actor Jeff Daniels watched practice Tuesday. . Detroit officially broke camp Tuesday, but Schwartz said a lot has changed from the days he began coaching in the NFL. "It used to be sort of a celebrated day in the NFL, breaking camp," he said. "Now they've got to check out of the hotel."
