SANTA CLARA, Calif. — Kyle Shanahan is ready to return to the sideline.The San Francisco 49ers head coach, a limited participant in training camp after suffering a concussion and other injuries in a July 14 car crash, said he’s feeling more like himself and plans to coach the team’s preseason opener against the Tennessee Titans next Thursday.“I can’t tell you guys how close it is. I’m getting there. And I will be there,” Shanahan said during an impromptu news conference.The appearance marked Shanahan’s first appearance at the podium since the crash, which he said is part of a push to do a little bit more every day. He’s already been doing film review since training camp began, and he addressed the team for the first time on Aug. 1.“The team meeting was a big step for me,” Shanahan said. “… As far as the important stuff, I feel like it’s 100 percent.”Since the beginning of training camp, assistant coach and longtime Shanahan assistant Chris Foerster has run practices, with offensive coordinator Klay Kubiak calling the plays for Brock Purdy and the rest of the quarterbacks.Shanahan has steadily been working his way back to full duty. When training camp first began, he stood well behind the defense next to general manager John Lynch and had little interaction.After about a week, he changed his vantage point and has been adding duties.“He’s inching closer,” quarterback Mac Jones said Thursday.Last month’s car crash in Palo Alto, Ca., which occurred when Shanahan turned into oncoming traffic while retrieving a fallen cell phone, left him with a concussion, broken ribs, a broken bone in his hand and a gash above his right eye that took more than 40 stitches to close. The driver of the other car wasn’t injured, and no one was cited, which Palo Alto police said was up to the discretion of the responding officer.Two weeks after the incident, Shanahan’s face looked fine, but the concussion symptoms lingered in the form of headaches, issues with noise and light, and fatigue.“I just can’t stay the hours right now,” he said during a small group interview in his office with reporters on July 28.Despite the odd circumstance, 49ers training camp has run smoothly, with Kubiak handling the offense and Raheem Morris, a former head coach, in charge of the defense. Foerster, the team’s offensive line coach, coached under Mike Shanahan in Washington for four seasons and has spent another seven years in San Francisco under Kyle, Mike’s son.Purdy, meanwhile, noted the roster is full of longtime 49ers, which also has made things easier.“We’ve been around the block and understand how this goes and what all goes into winning games in the NFL,” he said. “We have that. We have older guys that can help the young guys, and we can go through installs, we can go through practice, we can go through game prep and understand what it takes.”
