The Dallas Cowboys will kick off their 2019 preseason on Saturday evening when they travel up the coast to take on the San Francisco 49ers. The Cowboys traditionally play two west-coast teams while they are stationed in Oxnard, CA for training camp and this season is no exception.

The first preseason contest is rarely about the frontline starters, unless there is a high-profile rookie the club is looking to quickly get up to speed. That will be the case again on Saturday, but that doesn’t mean things will be less interesting for those who enjoy the competition for roster spots and identifying key youngsters who could be big-time contributors in years to come, or even possibly this campaign.

Here’s a look at 10 players to keep a close eye on Saturday night.

RDE Dorance Armstrong – second on depth chart, should start

Armstrong has had a really strong camp, and is likely to be the biggest beneficiary to Robert Quinn's 2-game suspension.

LDE Joe Jackson – third on depth chart

Jackson started camp slowly, but has been putting together a solid week in Oxnard, besting La'el Collins on a few drills.

QB4 Taryn Christion

Christion's a camp body with a strong arm, and is the only QB who has similar physical attributes as QB1 Dak Prescott.

WR Jon'vea Johnson – Second on Depth Chart at X WR

Johnson has had a strong camp, but had a bad B/W scrimmage. Can he become the annual buzz WR?

DT Daniel Wise – 3rd Under Tackle on Depth Chart

Wise was a well-regarded UDFA who should've been drafted, but that only lasts for so long before pro evidence is needed.

LB Luke Gifford – 3rd team Strongside LB

The UDFA is in on first-team punt coverage, a big deal for his chances of making the 53. Dislocated finger on Aug 6.

Slot CB Donovan Olumba – 2nd on depth

Olumba is an impressive specimen having good camp but at deep position will need game greatness to make roster.

FS Darian Thompson - 2nd on depth chart

Thompson has the size Richard loves and was on first-team when Woods was out. Can he hold off rookie Donovan Wilson?

ZWR Devin Smith - Third on Depth Chart

After injuries derailed early career, Smith is trying to make a roster with solid, youthful depth. He'll need to shine to move up in coach's eyes.

Left OT Mitch Hyatt - 3rd on Depth Chart
