SANTA CLARA, Calif. (AP) The San Francisco 49ers addressed a big need on their offensive line, trading with Kansas City for another first-round pick to select Stanford guard Joshua Garnett with the 28th choice Thursday night.

Garnett started 14 games for the Rose Bowl champion Cardinal at left guard last season, playing in front of record-setting running back and AP Player of the Year Christian McCaffrey.

Garnett could make an immediate impact on an offensive line that lost left guard Alex Boone to Minnesota in free agency.

The 49ers received the 28th pick as well as No. 249 in the seventh round, while the Chiefs got the 37th selection in the second round, 105 in the fourth and the 178th choice in the sixth.

Garnett became the 22nd first-round pick in Stanford program history.
