It was a sign of progress, but coach Bruce Arians said there is still not an estimate on when Floyd will return.
"He’s doing extremely well, so no, I don’t think there is an exact timetable," Arians said. "I wouldn’t be shocked if he’s ready (for Week 1), knowing Michael."
The Cardinals open the regular season Sept. 13 at home against New Orleans.
Floyd’s stitches were removed on Aug. 18, almost two weeks after he had surgery to repair three dislocated fingers in his left hand. Floyd has been working on his conditioning with assistant strength and conditioning coach Roger Kingdom before and after practices.
