Unfortunately, it looks like there will not be an official announcement today, as the team took today off to travel to Minnesota.
Three to four weeks, which if confirmed true, will put his return anywhere between the Rangers game against the Boston Bruins on November 25th, or the second matchup against the Nashville Predators, December 2nd.
The Rangers do have a six day rest period of no games between November 12-18, so it'll be less games missed with hopefully ample time to recover for him, and for the team.
We will update more information, and on the recall from the Wolf Pack, when they are made available.
