Santa Clara, CA (SportsNetwork.com) - San Francisco 49ers starting fullback Bruce Miller may miss the remainder of the season with a scapula injury he sustained in Sunday's 33-14 win over the Tampa Bay Buccaneers.

The team did not say if the third-year pro will be sidelined for the rest of the year, but head coach Jim Harbaugh said the injury "doesn't look good."

Miller, 26, has started 13 games for the 49ers this season, carrying the ball 25 times for 243 yards while paving the way for running back Frank Gore, who's rushed for 1,017 yards so far this season.

The 49ers host Atlanta next Monday before wrapping up the regular season at home against Arizona on Dec. 29.
