Initial testing on Alexander's right knee injury Monday did not reveal any significant concerns, and the Packers will continue to monitor his soreness throughout the week, Rob Demovsky of ESPN.com reports.
The cornerback sustained the injury late in Sunday's win over the Jaguars, but Demovsky's report suggests Alexander avoided what could have been a serious issue. His practice participation throughout the week will likely provide the best indication on whether he can play in this Sunday's matchup with the Lions.
