The Detroit Lions were expected by many to go out and find a running back at the NFL trade deadline, and that's exactly what they did. ESPN's Adam Schefter reports that the Lions have traded running back Jerome Harrison and a 2013 seventh-round pick to the Philadelphia Eagles for running back Ronnie Brown.

The Lions originally picked up Harrison in training camp after Mikel Leshoure went down with a season-ending injury. Harrison and Mike Bell signed shortly after, and Harrison won a spot on the team with his play during training camp.

During the 2011 season, Harrison only appeared in four games for the Lions. He rushed for 41 yards on 14 attempts and hasn't had a carry since Week 3 against the Vikings. He became expendable, and the Lions obviously believe Brown will serve as an upgrade, which is why they sent Harrison to the Eagles. (Side note: This is the second straight season Harrison has been traded to the Eagles. He was dealt to Philadelphia almost exactly a year ago by the Browns.)

Brown joined the Eagles after spending six years with the Miami Dolphins. He has only rushed for 38 yards on 13 attempts this season. His most notable moment this year was his puzzling fumble on the goal line against the 49ers. Hopefully things will go better for him in Detroit.
