The Lions added an eighth and final member to their practice squad today, signing tight end Joe Jon Finley (or J.J. Finley, depending on which site you reference).
Finley has been in the league since 2008, when he signed with the 49ers as an undrafted free agent. It appears he was with the 49ers from 2008 to this past Saturday, but he never appeared in a game or anything, so he still is eligible for the practice squad.
With Finely's addition, the Lions' practice squad now looks like this:
WR Tim Toone
WR Mike Moore
TE Joe Jon Finley
C Dan Gerberry
DT Robert Callaway
LB Caleb Campbell
CB Jonathan Hefney
CB Paul Pratt
