The Packers might be without first-year receiver Kevin Dorsey for the rest of the season after he suffered a significant foot injury during practice Thursday, according to McCarthy.
McCarthy said he'll miss "multiple weeks" and a decision hasn't been made on whether the former seventh-round pick will be placed on injured reserve.
Dorsey has played in three games with one catch for 4 yards since his Oct. 6 activation from the practice squad. He missed his rookie season with a toe injury.
The Packers didn't make any transactions Friday, but could promote receiver Myles White in his place or activate one of their three linemen — tackle Jeremy Vujnovich, guard Josh Walker or guard Jordan McCray — today if needed.
