The preseason is always about depth players being able to find roster spots or starting jobs by showing how well they perform in big game settings. The San Francisco 49ers have been hit by the injury bug early in training camp, resulting in these four players who had prime chances to flash sitting out.

Pro Football Network agrees. PFN listed Stout as the 49ers' one must-watch player during their Saturday night preseason tilt against the Denver Broncos.

The Niners held a joint practice with the Broncos on Thursday ahead of the preseason opener. San Francisco’s starters, including the newly extended Brock Purdy are likely to sit out most if not all of the game.
