"It’s kind of a disappointment, obviously, because he’s such a good football player and he’s played really well," Harbaugh said. "I’m so glad we were able to bring Chris Canty back this year."
Canty was released this past offseason and re-signed to a smaller, two-year contract that allowed him to return to the team and mentor the young defensive line that features Brandon Williams, Lawrence Guy, Timmy Jernigan, Carl Davis, Kapron Lewis-Moore and Brent Urban.
He missed four games with a calf injury this season, but has been a constant presence around the team.
"He’s played really great football, but more than that he’s been a tremendous leader," Harbaugh said. "He’s been a standup guy. He’s led the way with a bunch of young guys on defense, especially the young front seven guys. I have nothing but the utmost respect for Chris Canty and what he’s done this year."
His absence going forward could mean more opportunities for Davis, a rookie third-round NFL draft pick who has been inactive for the past three games, and Lewis-Moore, who has sat for the past six games and hasn't played since Canty returned from his calf injury.
"I saw [Davis] in the locker room along with Kapron yesterday they’ve handled it well, but those guys want to play," Harbaugh said. "Carl’s had a couple weeks off to kind of study, and he’s been practicing, but let’s see if he takes his game up a notch after being out for a couple weeks."
