Minnesota Vikings coach Leslie Frazier said Friday that Christian Ponder will be the Vikings' starting quarterback on Sunday night against the Green Bay Packers.
Josh Freeman, meanwhile, will not play because of a concussion he sustained in his first start with the team Monday against the New York Giants.
Freeman has passed some of the NFL's concussion tests, but has not been cleared to play. Former NFL player and current NBC analyst Rodney Harrison questioned Freeman's injury on Thursday, implying that he is faking. Freeman responded to Harrison's claims by saying, "All I can do is live in my truth."
Frazier said he saw no signs of Freeman's head injury during the loss to the Giants. Freeman struggled, completing 20 of 53 passes for 193 yards with an interception.
Freeman thinks the injury occurred during the third quarter but said he never told the team about any symptoms until Tuesday.
---Brett Favre told Washington radio station WSPZ-AM on Thursday that he fears he is experiencing symptoms related to concussions he sustained during his 20-year NFL career.
Favre's concern about memory loss was raised in the interview in which he said the St. Louis Rams reached out to him about playing for them.
"I don't remember my daughter playing soccer, playing youth soccer, one summer," he said.
Favre said in the interview that he has no interest in coming back.
---Former NFL defensive lineman Reggie Rogers was found dead Thursday in Seattle, according to multiple reports. He was 49.

In 1988, Rogers killed three teenagers in a drunk-driving accident. His blood-alcohol level was more than double the legal limit. He served a year in prison.

Nick Foles, who filled in for Vick, is ruled out for this week because of a concussion.
---New Orleans Saints tight end Jimmy Graham and running back Mark Ingram returned to practice, and both are listed as questionable for Sunday's game against the Buffalo Bills.
