Packers' Don Jackson: Signs ERFA tender

Jackson (knee) signed his exclusive-rights contract tender with the Packers on Wednesday, ESPN's Jason Wilde reports.

By officially putting pen to paper Wednesday, Jackson joins a shallow running back corps comprised of only Ty Montgomery (ribs) and Christine Michael. However, the Packers likely aren't done adding talent, and Jackson could thus find himself competing for a roster spot this summer if the team spends a high pick or two at the position in this year's draft.
