Pittsburgh Steelers quarterback Ben Roethlisberger is doubling down on his future with the team.

He posted a Christmas message Wednesday morning on Twitter with a picture of his family but followed up later, saying:

"P.S. Contrary to recent reports out there about my football future and my 'uncertainty' about playing again, I am working hard and am more determined than ever to come back stronger and better than ever next year!"

Roethlisberger has been sidelined since suffering an elbow injury in week two against the Seattle Seahawks.

He did not give a timetable but is serious about making a full recovery.
