Delmas had surgery on his left knee Aug. 7 and although he was limited in practice, he did not wear a brace on his knee.
The Lions have been cautious with the 25-year-old safety.
"I could've practiced last week," Delmas told the Detroit Free Press. "Yeah, I felt good out there."
The Lions have a bye this week and their next game isn't until Oct. 14 when they visit the Philadelphia Eagles. It’s possible that Delmas could make his season debut against the Eagles.
"He only did individual today, but he did it at a high-level," said Jim Schwartz. However, the coach did say it was "too soon to tell," whether Delmas would be ready to play against the Eagles (via Detroit Free Press).
Delmas appeared in Detroit’s first 11 games last season, but missed the last five because of an injured right knee that required surgery. Despite missing five games, Delmas was named an alternate for the Pro Bowl for a second consecutive year.
In 2009, Delmas became the first rookie in NFL history and only the second player ever to record a safety, an interception return for a TD and a fumble recovery for a TD in one season.
