The 49ers had a private with UTEP running back Aaron Jones earlier this month, according to a league source.
Jones (5-9, 208 pounds) ranked fourth in the FBS last season with 1,773 rushing yards on 229 carries. He scored 17 touchdowns on the ground with another three coming on receptions. He had runs of 83, 75, 68 and 62 yards last season. Jones finished among the Top 3 running backs at the scouting combine this month in the vertical jump, broad jump, the three-cone drill and the 20-yard and 60-yard shuttles.
The 49ers currently have four tailbacks -- Carlos Hyde, DuJuan Harris, Mike Davis and Raheem Mostert -- signed for the upcoming season but are open to adding at least one more runner in the draft.
