Reid said he suffered two concussions in the first nine games of his rookie year, without missing any time. He sat out last season's final game, even though doctors had cleared him to play.
Reid decided to return to the team, despite the concussion risk.
"Everybody evaluates their own situation as far as playing this game," Reid told The San Francisco Chronicle. "I've evaluated mine and I've decided I still want to play."
Reid said that he wouldn't necessarily retire, even if he suffered another head injury.
"I'm not putting a number to it," he said. "I will continue to evaluate my own situation."
Hyde, Stevie Johnson and Reid were all ruled out prior to Sunday. Brock, Brooks and Cox were all considered questionable. Brock has a hamstring injury. Brooks is dealing with a thumb issue. Cox has a shoulder injury. Josh Johnson is a healthy scratch.
It is the second straight game out for both Hyde and Johnson. Hyde finishes his rooke season with 83 carries for 333 yards and four touchdowns while Johnson had 35 catches for 435 yards and three touchdowns this year.
The 49ers are currently 6 1/2-point favorites against Arizona Sunday.
"We've kept the doctors busy," coach Jim Harbaugh said.
The 49ers are currently 6-point favorites against the Cardinals, according to Vegas Insiders.
The concussion is Reid's third in the last two seasons. He'll have to pass concussion protocol before being allowed back on the practice field or back in the lineup in Week 17.
