The Detroit Lions have placed quarterback Jeff Driskel on injured reserve and signed quarterback Kyle Sloter off Arizona's practice squad -- another signal-caller move for a team that has been rotating quarterbacks behind Matthew Stafford since the end of last season.
Sloter and just-signed practice squad quarterback Joe Callahan are the 10th and 11th quarterbacks the Lions have had on the roster this season. Stafford, Driskel, David Blough, Josh Johnson and now Sloter have been on the active roster. David Fales, Tom Savage and Luis Perez were with the team in training camp and Connor Cook was on Detroit for spring workouts.
