The Cowboys are losing yet another player to the Reserve/COVID-19 List. Dallas placed linebacker Keanu Neal on the list Wednesday, just as defensive tackle Randy Gregory was being activated from it. Neal is now questionable to play in the team's home opener against the Eagles on Monday. He will have clear protocol in time, but Gregory, Zack Martin and Brandon Knight all missed a game because they weren't able to. Additionally, the Cowboys signed cornerback Holton Hill to their practice squad on Wednesday.
