The San Francisco 49ers held out a couple of rookies Saturday night against the Denver Broncos in their first preseason game. Head coach Kyle Shanahan shared his reasons why and provided injury updates during his postgame press conference.

Denver Broncos outside linebacker Nik Bonitto had a dominating series against the San Francisco 49ers on Saturday evening. Bonitto sacked quarterback Mac Jones on first down, shared a sack with John Franklin-Myers on second down, then forced an incompletion on third down. The edge defender essentially killed a 49ers drive single-handedly.
