Coach Doug Marrone said third-round TE Josh Oliver suffered a "serious" hamstring injury in Thursday's practice.
A standout in spring practices, Oliver hadn't made much noise to this point in camp. The rookie easily possesses the most upside in this tight end group, but it sounds like he's going to miss multiple weeks at minimum. Geoff Swaim and James O'Shaugnessy are next up on the depth chart.
He may not have made a huge impact this season but this is a guy they were really hoping would develop into a solid TE
