Coach McCarthy on Thursday compared Ferguson's injury to defensive tackle Kenderick Allen, who went on injured reserve last week after sustaining the injury against the Detroit Lions.
McCarthy said the team will get a better idea of Ferguson's recovery when the players return for practice on Monday.
Ferguson injured his foot returning a kickoff in the fourth quarter of Green Bay's loss to the Philadelphia Eagles on Oct. 2. He missed last Sunday's game against St. Louis, but feels he can bounce back from the injury.
"A few guys went on injured reserve with a similar type of injury, but I'm putting it on me because everyone heals different," Ferguson said. "I'm telling the coaches and the trainers not to count me out and keep that IR word out of it. We'll wait and see how I react to it."
Ferguson had knee injuries that limited him to 11 games in 2005 with just seven starts. He also was limited in 2004 due to injuries.
While Ferguson's season appears to be over, rookie cornerback Will Blackmon is still trying to get his started. Blackmon took part in his first team drills of the season Thursday morning.
Blackmon missed all of training camp with a broken foot that he sustained on May 21 in a minicamp practice. He also has missed the first five regular season games as well.
"It felt like a year. The last time I went full go with pads was the Senior Bowl," Blackmon said. "It's a huge step. I'm hoping to make the same progress that I made last week into next week, then I hope to get things rolling."
Cornerback Charles Woodson (quadriceps) and receiver Koren Robinson (knee) did not practice on Thursday. Others who missed practice and likely will be questionable for the Miami game were: linebacker Abdul Hodge (knee), linebacker Ben Taylor (hamstring) and defensive tackle Cullen Jenkins (ankle).
McCarthy said that he is hoping Hodge will be ready to return by Green Bay's home game against Arizona on Oct. 29. Hodge also was injured while playing on special teams Oct. 2 against the Eagles.
"He's ready to go and wants to get off the crutches," said McCarthy. "This will be good for him to get away and get off of it. I'm hopeful he'll be back, if not Miami maybe the following week."
Will Blackmon looks on during a training camp practice in August.
