Zack Ryder continues to train at the WWE Performance Center to prepare for his in-ring return since suffering a knee injury back in December. He revealed on Twitter that he recently hit his finisher for the first time since he suffered the injury.

As noted, Ryder was diagnosed to be out of action for 4-6 months. Zack being able to work the ropes and hit his finisher is a strong indication that he could be returning to in-ring competition very soon.
