Replacing Toone on the practice squad is wide receiver Alric Arnett. He was an undrafted free agent out of West Virginia who originally signed with the Colts.
In other injury news, the Lions were once again without Tony Scheffler and DeAndre Levy at practice today. Levy is dealing with an ankle injury, whereas Scheffler is recovering from a concussion he suffered against Green Bay.
The good news from today's practice is that C.C. Brown and Sammie Hill returned, joining Louis Delmas, Jahvid Best and Nate Burleson, who all practiced for the second straight day this week.
UPDATE: Chris McCosky is now reporting that Brown did not practice after all.
