The San Francisco 49ers may have to alter course on their plan to play starters in the preseason vs. the Las Vegas Raiders.

After only playing in four games last season, McCaffrey is aiming to make a massive comeback to help get the Niners back in the playoffs.

Kyle Shanahan has been impressed with wide receiver Ricky Pearsall during the 49ers’ training camp this season. There’s growing concern surrounding the 49ers’ wide receiver position heading into the new season, as San Francisco prepares to kick off preseason on Saturday at Levi’s Stadium against the Denver Broncos.
