Tolbert (hamstring) got significant reps during Tuesday's mandatory minicamp, David Helman of the Cowboys' official site reports.
The rookie wideout had been nursing a hamstring injury during OTAs, but he appears to have moved past the issue and looks poised to carve out a role in Dallas. With Michael Gallup (knee) potentially unavailable for Week 1, Tolbert will compete with fellow newcomer James Washington (foot) for snaps and targets behind No. 1 wideout CeeDee Lamb.
