Whether McNabb or the man that replaced him, rookie Christian Ponder, will be under center when Minnesota hosts Green Bay next Sunday remains uncertain.
"We have to sit down on Monday and talk about a lot of things," coach Leslie Frazier said after the 39-10 loss. "We need to decide on that direction we want to go."
McNabb was 19 for 24 for 177 yards before being removed and Frazier said he wanted to get Ponder some NFL experience in a game that was already out of hand.
"We just wanted to get him in there, let him take some snaps and get a feel for the NFL tempo," Frazier said."
Ponder was Minnesota's first round pick (12th overall) in April's draft. The former Florida State Seminole completed 9 of 17 passes for 99 yards in his NFL debut.
For his part, McNabb was complimentary of how Ponder handled his first taste of a regular season game.
"I thought he did a great job," McNabb said. "Obviously when you are coming in late in the game in that situation it's tough. I thought he did a great job moving the guys down the field. I thought he handled it well."
Ponder shied away when asked if he thought he would get the call against the unbeaten Packers.
"I don't know," Ponder said. "I know I missed a couple of plays I know I missed a couple of plays so that's the coaches' call."
McNabb has struggled greatly since leaving Philadelphia after the 2009 season. He was benched last year in Washington after being acquired in an offseason trade by new coach Mike Shanahan. The Vikings then traded for McNabb when the lockout ended, but the former Pro Bowler has failed to impress and was recently booed by the home fans.
Minnesota has stumbled to a 1-5 record in Leslie Frazier's first full season as coach, but McNabb was defiant when asked if he had thought about his well-decorated NFL career ending "like this."
"It's tough, you're 1-5 at this particular point," the 34-year old said. "It felt like we did a lot of great things today. I guess we'll sit down and talk but I expect to be in there next week."
Entering Sunday's game, McNabb had completed only 56.8 percent of his passes for just 849 yards. Both of those totals rank in the bottom six among NFL starting quarterbacks this year.
