Driskel (hamstring) was listed as a limited participant on Monday's practice estimate, Michael Rothstein of ESPN.com reports.
This is tough news for the Lions, as they'll be on a short practice week ahead of Thursday's matchup against the Bears. Driskel has two more practices to get to full speed. If he can't shake the issue, David Blough -- an undrafted rookie out of Purdue -- is in line to make his NFL debut.
