On Monday, Chargers first-round pick Joey Bosa signed a four-year contract with the team after ending a holdout that started in June.
On Tuesday, he got on the field and got to work.
Bosa has some catching up to do after missing the majority of the preseason and all four exhibition games. The last time he practiced with his teammates was three months ago, during organized team activities, and the defense has made major advancements since that time. Bosa has yet to put on pads -- which will be more of a benchmark of where he's at physically -- but he was encouraged by his teammates during drills on Tuesday and at one point, was embraced by them for a photo in front of media (egged on by veteran Brandon Mebane).
"He just has to get in here and learn the defense," said defensive end Corey Liuget. "I'm glad he's here. [Now just] see how he is as a football player with pads and everything, and then go from there."
When asked what Bosa could do to accelerate the process, Liuget was quick to reply with one piece of advice: Study.
"Just study," he said. "Just study the playbook. That's the only thing he can do. He looks like he's in pretty good shape, but he just needs to study the playbook."
Bosa is doing just that, actually. He met after-hours Monday with defensive line coach Giff Smith to try to accelerate the learning process, and said he will do so again Tuesday. Although Bosa has been ruled out for the fourth and final preseason game, there is a possibility he will be ready for the season opener in Kansas City on Sept. 11, if even in a limited role.
For now, Bosa can only work.
"He looked as expected," said head coach Mike McCoy after Tuesday's practice. "In shape, ready to roll. A guy who loves to play — the energy, the passion he comes to work with every day. He was that way all day [Monday], whether it was in the weight room, in the meetings, whatever it was. You go out there and see him go through individual drills [and] he looked like the way he did when he left."
The Chargers will hold a walk-through at MCAS Miramar on Wednesday before playing the 49ers at Qualcomm Stadium on Thursday evening.
