San Francisco signed Pettis to its practice squad Tuesday, Matt Maiocco of NBC Sports Bay Area reports.
The 49ers must have liked what they saw when they worked out Pettis on Tuesday, as he's now already a member of their practice squad. The team is dealing with injuries to more than a few of its wide receivers, including veterans Mike Evans (ribs) and Demarcus Robinson (ankle), so Pettis could see himself elevated to the active roster relatively soon.
