Barclay Goodrow appears to leaves bloody piece of his face on ice

In tonight's game against the Ottawa Senators, Goodrow was struck by a puck. As the puck comes out of the zone teammat K'Andre Miller attempts to keep the puck in the zone. Unfortunately the puck strikes Goodrow in the face and send him immediately to the ice.

On a closed examination, Twitter account Scouting the Refs points out it appears Goodrow may have left a piece of himself on the ice.

This item appears much too small to be a mouthguard and has left fans puzzled. What do you think it is?

Update

The Rangers have announced Goodrow will not return.
