SANTA CLARA, Calif. (AP) — The San Francisco 49ers defense had a different feel once star edge rusher Nick Bosa returned to practice. Now the Niners can’t wait to see Bosa’s dominance in a game when he returns from a knee injury in the season opener at Detroit on Sunday. Linebacker Fred Warner calls Bosa a “game wrecker” who has the ability to destroy offensive game plans. That was lacking last season for San Francisco after Bosa went down with a torn ACL in Week 2.
