(WNFL) - Green Bay Packers' coach Mike McCarthy has not said who he'll start at quarterback on Thursday at Detroit -- but he won't take long to decide. If Aaron Rodgers doesn't return, Matt Flynn would appear to be in the driver's seat. Flynn threw for 218 yards and a touchdown in relief of Scott Tolzien in the second half and the overtime of yesterday's tie with Minnesota. Flynn learned the Packers' no-huddle offense when he spent four seasons as a backup to Rodgers through 2011 -- and McCarthy wasn't afraid to use it at times yesterday. Still, the Packers remain winless in four games after Rodgers' broke his left collarbone on November fourth against Chicago. It dropped Green Bay's record to 5-5-and-1, 10th best in the N-F-C and a half-game behind North Division leaders Chicago and Detroit. McCarthy says he's been hesitant to publicly admit that his team has not handled Rodgers' departure. But he came out with that yesterday, and said everyone needs to step up and take advantage of their opportunities. McCarthy said the Packers let one slip away yesterday.
