As the Dallas Cowboys get ready for the 2020 season there is a big problem hanging over the league, COVID-19. The hope was initially that there would be a vaccine or it would disappear before the start of the NFL season, but it doesn't appear that is going to happen.

Once the NFL season starts, there will likely be positive tests, but the NFL hopes that they can get those players isolated and continue the season. The Cowboys don't want to lose someone like quarterback Dak Prescott for any period of time, but that is obvious given the position he plays and he won't be included on this list. Let's take a look at three players the Cowboys can't afford to lose who may be more under-the-radar.

Tyron Smith

Keeping Prescott upright is of utmost importance this season, and losing Tyron Smith for even a couple of weeks would be a devastating blow to the Cowboys offense. Left tackle is one of the most important positions on the entire team. If Smith were to go down, it would probably be Mitch Hyatt who would have to fill in. He was an undrafted free agent out of Clemson who signed with the team in 2019. He was on the active roster for the end of the Cowboys' 2019 season after spending most of the year on the practice squad, but he isn't anywhere close to Smith's talent level.

Michael Gallup

Micheel Gallup is a game changer for the Cowboys offense, and yet another player the team can't afford to lose. Gallup is a deep-ball specialist who can take the top off the defense. Last season, Gallup caught 66 passes for 1,107 yards and six touchdowns. Gallup draws attention from the defense which also helps keep some of the pressure off Amari Cooper. If Gallup goes down with injuries it's going to put a lot more eyes back on Cooper, which is going to hurt the effectiveness of the Cowboys offense.

Ha Ha Clinton-Dix

Ha Ha Clinton-Dix hasn't even played a down with the Cowboys yet, having been signed this offseason, but he is going to be a key part of the defense. Clinton-Dix is expected to start at strong safety for the team, and after him, there isn't a whole lot of depth. Donovan Wilson was a sixth-round pick in the 2019 draft. If he gets thrown in as a starter, the secondary is going to be in some trouble

Clinton-Dix might not be the best safety in the league, but for the Cowboys he is going to be a key player.
