What happened: San Francisco is reuniting with its 2016 first-round pick six years after dealing him to Indianapolis in 2020, per Field Yates. The acquisition reinforces an injury-depleted defensive front that has Alfred Collins on injured reserve and Nick Bosa listed as questionable while managing a calf injury.

Why it matters: The 49ers hold the No. 2 seed at 6-1 as they bolster their interior pass rush for the second half of the regular season. Sitting 12th in the conference at 2-5 on a three-game losing streak, the Colts are moving veteran pieces ahead of the Nov. 10 trade deadline.

What to watch: Buckner joins the 49ers ahead of Week 8 while Bosa has a chance to return to action in November.
