The Lions didn't elevate Rosas from their practice squad for Thursday's game against Chicago, likely leaving Riley Patterson as the placekicker, Dave Birkett of the Detroit Free Press reports.
Rosas played four games for the Saints earlier this season and made both of his kicks (an extra-point try and a 43-yard field goal) last week in his Lions debut. He reverted to the Lions' practice squad following the contest, leaving Patterson as the lone kicker on the 53-man roster. Patterson is now in line to make his NFL debut Thanksgiving Day.
