Coach Mike McCarthy told reporters today that Blackmon injured his foot, the same foot that he injured as a rookie last season, in the final team drill during Wednesday's practice. McCarthy didn't say how long Blackmon will be sidelined, but it's a good bet that he will miss the remainder of the season.
If Blackmon is placed on injured reserve, it will mark the second straight year that he has finished the season on that list. Last year, Blackmon was placed on IR with a rib injury on Nov. 25.
"It was very unfortunate," McCarthy said. "I feel terrible for Will. Will was coming on strong."
Blackmon was set to return punts and kickoffs this season after an impressive showing in the preseason, but he injured his thumb late in the preseason and has had to wear a cast in the first four games of the regular season.
"We all saw what he did as a returner, and we felt that he and Jarrett Bush were right there neck-and-neck as the No. 3 corner," McCarthy said. "It's a shame, because he was contributing on special teams and was really making a move."
Blackmon has been used in the team's dime defenses this season. He likely will be replaced by Tramon Williams, though, the Packers may opt to use veteran Frank Walker a little more in the dime packages. The guess here is that the Packers will go with Williams as the No. 4 cornerback behind Al Harris, Charles Woodson and Jarrett Bush.
