Colin Kaepernick will miss his second straight preseason game when the 49ers face the Broncos on Saturday night, though there is some good news on the horizon. First-year coach Chip Kelly says the embattled quarterback will return to action soon.

"We have a plan for him going forward," Kelly said, via's Matt Maiocco. "They're easing him back into throwing right now. In talking to him, he said he feels really good about it. But we don't want to throw him back out there and have a set back right now.

"As we said before, from what we understand, it's not a long-term thing. He'll throw a little more today and see how he feels and continue to progress him and hopefully we can get him back full next week."

Kaepernick hasn't practiced since Aug. 10 because of a tired arm -- which shouldn't be mistaken for a dead arm. General manager Trent Baalke addressed the difference on Wednesday.

"I don't know what dead-arm syndrome means," Baalke told reporters, via the "His arm's tired. To say it's dead, I wouldn't make that assumption. It's like a pitcher. He hasn't thrown a lot in the offseason because of the injuries he was overcoming, the rehab he was under and the protocols he was faced with in rehab. Right now, he threw a lot of balls early, and he just needed time to give it a little bit of a rest, and that's where he's at."

Meanwhile, Blaine Gabbert remains the default starter, though there are no guarantees he wins the job outright. Kelly admitted this offseason to being intrigued by Gabbert's physical skills, but the Jaguars' former first-round pick was inconsistent in the preseason opener.

The rest of the 49ers' depth chart includes Jeff Driskel and just-signed Christian Ponder, who replaces Thad Lewis after he suffered a torn ACL during the first preseason game.
