On if all the starters will sit out against San Francisco:
"I wouldn't say all. We're going to sit some people, yeah. We're still trying to figure out who the starters are going to be in some positions. Right now, I can't say that we're going to sit all the starters."
On S Derwin James:
"We plan on Derwin playing, yes."
On G Forrest Lamp:
"The plan is to play Forrest this game. I'm not sure how much, but the plan is definitely to get him in."
On how much Lamp could play:
"He hasn't played football in a long time so we can't put him out there for four quarters, for sure. Maybe give him a couple series and see how he feels. If he feels like he can go three [quarters] or maybe the first half, that's possible, but we'll see."
On if the team has started looking to the season opener against Kansas City:
"It's hard because you want to, but we really have to focus on the Niners — not so much scheme-wise, just personnel-wise because we're trying to complete the roster on our football team. There are still some jobs on the line. Guys are going to be competing. That's kind of where my focus is right now."
On players on the bubble of making the roster:
"We've been reminding them of that all week and telling some inspirational stories of guys like [S] Adrian Phillips, who was a long shot to play in this league and he's going into his fifth year. A guy like [RB] Austin Ekeler, who made this team last year in this game. Those guys, they need to know that it's not over until it's over."
On if the fourth preseason game carries extra weight for the final roster spots:
"No. We look at the whole process, the big picture through the whole time that we've had you. The games definitely matter, but it's not just the last game."
On who he will be watching most closely on Thursday:
"I'm watching everybody, man. I'm watching my whole team closely."
On players competing for jobs:
"You still have guys that are competing.[LB] Kyzir White, [LB Jatavis] JB [Brown] and all of those guys. Who is going to be in the starting lineup day one? I'm looking at defensive lineman, looking at depth on the offensive line, looking at the backup quarterback position. I'm looking at the whole roster. There's always a surprise. Like last year, Austin Ekeler. He just kept improving over and over. Every time he was in the game, we would push the ball down the field and that wasn't an accident."
On keeping two quarterbacks compared to three on the active roster:
"[General Manager] Tom [Telesco] and I will sit down and we'll look at the big picture Friday and Saturday. We'll make those decisions after this game."
On QB Cardale Jones:
"He's better. He's definitely better. That's why we pulled him early last week. We didn't want him to hurt himself any further."
On DL Justin Jones:
"Now that he's back healthy and on the field, he has some tools. He's looking good. He's going to get some opportunities on Thursday night."
On being careful with Justin Jones:
"If he was on the roster and it was a game week, maybe [he would have played], but there was no reason to. We didn't want him to hurt himself last week and then not be able to play this week. That wouldn't do him any good."
On RB Justin Jackson:
"He looks good. [He has] fresh legs. He's moving well. He's making good cuts. He was doing really well before he got hurt. We're looking forward to seeing him get in the ball game and run, but we can't run him too much. We don't want to hurt him. He hasn't been in action for a long time, but he's going to play a lot."
