Mike Green has gone through four days of lengthy practices — three with teammates — and twice took part in a full session with drills and contact.

The defenseman is extremely close to making his return to the Capitals’ lineup after undergoing surgery to repair a tear in his stomach lining back on Jan. 17. General Manager George McPhee said Green will travel with the team to Florida for the beginning of its four-game road trip and maintained that the two-time Norris Trophy finalist could be back in the mix in the next few days.

“Could be this weekend, we’ll see,” McPhee said. “We discussed it a lot and we’ll discuss it again tomorrow and see how he feels after today.”

Green hasn’t played since Jan. 7 and has been limited to appearing in only 10 games this season because of multiple injuries. This week, though, the defenseman was noticeably optimistic about his recovery.

Based on Green’s comments as well as McPhee’s, don’t be surprised to see the defenseman back on the blueline at some point during the road trip.
