49ers' Tim Hightower: May be on bubble for roster berth

Hightower may be on the bubble for a roster spot with the 49ers, Matt Barrows of The Sacramento Bee reports.

Carlos Hyde and 2017 fourth-round pick Joe Williams entered camp as roster locks, and undrafted rookie Matt Breida has also made a strong push for a spot. Hightower may be competing against Raheem Mostert for one roster spot, with the battle potentially playing out during Thursday's preseason finale against the Chargers. Even if he does end up making the team, Hightower won't necessarily have a significant Week 1 role on offense.
