49ers defensive end Nick Bosa has missed five consecutive practices.
Coach Kyle Shanahan said earlier this week that Bosa was experiencing soreness as he returns from a torn ACL in his right knee. On Tuesday, Shanahan added tendinitis to the explanation for Bosa's recent absence.
"Just soreness, tendinitis," Shanahan said, via video from his news conference. "It's a pretty normal thing with ACLs. Talking to our guys, they say it happens with about 90 percent of the [time]. So, it's a normal thing. We've got to be smart here week to week, but no concerns about it being any more than that."
Bosa injured his knee in a Sept. 21 game against the Cardinals and underwent surgery Sept. 26.
Bosa, 28, has not had a double-digit sack season since 2023, which is the last time he played all 17 games. He has played only 17 games over the past two seasons, totaling 11 sacks.
