The Vikings agreed on the course of action with Cook and his agent, Hadley Engelhard, so the 24-year-old cornerback can focus on his off-the-field situation.
"We want him to put his energy and efforts into that case," Frazier said, sounding as if Cook already has played his last snap of the 2011 season. "It's hard to say that we're going to see him again considering what he's facing, but we'll see what happens."
Cook has a Nov. 22 court hearing regarding the allegation he strangled his girlfriend after becoming angry that she spoke with a former boyfriend. Frazier, however, stopped short of ruling Cook out of the team's future plans.
"It's so tough to say today as we stand here in November, considering the situation and not knowing how it's going to play out," the coach said. "It's hard to look into the future."
Cook could face discipline from the NFL under the league's personal-conduct policy. Spokesman Greg Aiello said Cook's situation remains "under review."
Engelhard hasn't returned messages seeking comment since his client's arrest more than two weeks ago.
"Hopefully the allegations aren't true. Hopefully he gets things turned around," Frazier said.
