SANTA CLARA — Colin Kaepernick says he “most definitely” has a chance to win back his starting quarterback job.

49ers coach Chip Kelly hasn’t publicly indicated otherwise, even though Kaepernick missed the first two exhibitions and over a week of practice with a sore shoulder.

“I’m going to go out and show everything I can these next two games,” Kaepernick said Wednesday, adding that he will “make sure I put my best foot forward to show this organization, this team, this coaching staff, what I’m capable of.”

Kaepernick’s return to practice this week has him poised to play in Friday’s home exhibition against the Green Bay Packers. Kelly said he’ll wait for the medical staff’s recommendations before deciding how much he’ll play Kaepernick, or if he’ll start Blaine Gabbert for a third straight game.

Kaepernick and Gabbert have split first-team reps in practice this week, just as they did for nine practices before Kaepernick’s throwing arm got cranky.

“It’s great to be back out there, great to be back practicing with my teammates and getting ready for this next game,” Kaepernick said. “Everything’s been going great, everything’s been going as planned, so excited to get out there this Friday.”

Kaepernick didn’t seem excited to talk about his relationship with general manager Trent Baalke, who said last week the two recently sat down for the first time since last season and had a “good conversation.”

“We had a conversation,” Kaepernick said, adding: “We have a business relationship. That’s the point that we’re at.”

Kaepernick sought a trade earlier this year amid his friction with the front office. His $11.9 million base salary is guaranteed this season, and it’s $10 million more than Gabbert will earn in the final year of his respective contract.

While Kaepernick’s health limited his offseason participation and interrupted the training-camp competition, Gabbert has had more opportunities to showcase his first-string capabilities. Through two exhibitions, Gabbert completed 10-of-19 passes for 132 yards and a touchdown, with no sacks, no interceptions and no fumbles.

“I’m just worried about the things I can control, the things I put on the field and the way I lead these guys and lead this football team,” Gabbert said.

Added Kaepernick: “I can only worry about myself. I focus on the reps that I get and the mental reps that I’ve taken, so when I step on the field, I feel I’m very prepared.”

Kelly would only go so far as to say Kaepernick is “on track” and they’re “hopeful” he can play, as long as the 49ers medical staff clears him for his first game action since November, when he went on injured reserve with a left-shoulder injury.

“He’s been sharp with all things mentally,” Kelly said. “There’s always a little bit, when you take some time off physically, there may be a ball that was behind from a timing standpoint. But there’s been no indecision in terms of he doesn’t know where he’s going with the ball.”

Kaepernick didn’t fully participate in practice from Aug. 11 until this past Monday, citing a tight shoulder that he compared to an issue he experienced as a high school pitcher. “At this point, I would say I bounce back quicker than I did in the past,” Kaepernick said. “Baseball’s very taxing on a shoulder. Football, not as much.”

The 49ers have introduced three robotic tackling dummies into practice, and although Kelly and several players hailed the helpful technology, one player wants no part of it. That would be linebacker NaVorro Bowman, the NFL’s leading tackler last season. “I don’t want to (tackle them),” Bowman said with a laugh. “One guy tried and it didn’t turn out too well for him. He tried to tackle the robot and it tackled him.” It’s not just defenders who can use the padded, robotic dummies to work on technique. Offensive linemen performed cut blocks on the $8,000 Mobile Virtual Player dummies Tuesday. “I like the concept of them, and I didn’t realize they’d be so quick,” center Daniel Kilgore said. “It’s great, the technology they’re using for us here.” Five other teams have the MVP dummies that were dreamed up by Buddy Teevens, the former Stanford and current Dartmouth coach.

Rookie wide receiver Bryce Treggs, a Cal product, said he is week-to-week in returning from a medial collateral ligament sprain in his left knee.
