Gallup sustained a strained left calf during Thursday's loss at Tampa Bay and will be sidelined 3-to-5 weeks, Michael Gehlken of The Dallas Morning News reports.
Gallup exited in the second half Thursday with what was termed a left ankle issue at the time, but upon further evaluation the nature of the injury has been confirmed. The Cowboys thus won't have the fourth-year wide receiver available again until October, with his recovery ultimately determining when he gets back on the field. In the meantime, Amari Cooper and CeeDee Lamb should see plenty of volume, while Cedrick Wilson gets a boost in targets as well.
