Green, who has been out for the majority of the last three months with a groin injury, has led the Capitals to a 9-1-0 record while he is in the lineup. Washington placed him on long-term injured reserve earlier in the week, which would have meant that the earliest he could re-join the team was February 1st. He will not be able to play now for at least two weeks beyond that, and probably much longer.
The abdominal surgery does have the goal of fixing Green's groin problem; this is not believed to be a aurgery that is the direct result of a new injury.
The Calgary, Alberta native has three goals and three assists in his ten games this year.
