Will Blackmon, the Packers' second-year cornerback, was placed on injured reserve after breaking his right foot in practice. Coach Mike McCarthy revealed the injury following Thursday's practice.

Blackmon, who broke the same foot during a May 2006 minicamp, was covering a receiver during the final 11-on-11 team period of Wednesday's practice when they got their feet tangled up.

Blackmon came back from a foot injury after missing the first five games of last season, only to suffer a broken rib in his fourth game on the active roster and winding up on IR.
