Right guard Dominick Puni and running back Corey Kiner sustained significant injuries in the first half of the 49ers’ preseason visit to the Raiders on Saturday.

Puni, a third-round pick of the 49ers last year, played a key role for the team as a rookie. The 25-year-old played a team-high 1,078 offensive snaps, allowing just three sacks, along with 35 pressures and 32 hurries, according to Pro Football Focus.

This NFL expert analyst would say that the 49ers' wide receiver problem isn't as big of a deal as it's made out to be.
