The San Francisco 49ers play three preseason games in 14 days. Head coach Kyle Shanahan spoke to reporters ahead of Tuesday’s practice and outlined his plan to ensure starters get exposure reps without burning out. For the second-year quarterback Trey Lancethat means playing in just two pre-season games.

“We have a pretty good idea [for the preseason plan]”, Shanahan said. “I really want to see how these practices go these first two days. I would like the guys to play in this game, mainly because I don’t want them to play in the second game.”

On Friday, the 49ers will host the Green Bay Packers at Levi’s Stadium. Then, eight days later, they will face the Minnesota Vikings on the road. San Francisco will practice with the Vikings the week before this game, which is far more important to Shanahan than the exhibition game. In fact, the coach went so far as to say that he would rather only do joint training and eliminate pre-season games.

Then, five days after facing the Vikings, the 49ers will play on the road against the Houston Texans. Playing the Vikings and then the Texans would be tough.

“That’s why I don’t want them to play a lot in this game,” Shanahan explained. “Hopefully a little in one, a little in three, and then we’ll have 17 days to prepare for Week 1. … In my mind, right now, I would like Trey to come in, Games One and Three. “

Shanahan admits he hasn’t thought about how badly he wants to see Lance play in those two preseason games. As for the starting offensive line, he said, “I want at least a few.”

The 49ers coach was asked about his assessment of Lance so far during training camp. After all, there’s been a lot of talk about the quarterback’s top-down practices.

“He left as expected,” Shanahan said. “…I think he’s had some really good days. He’s had a few tough days. I thought he had a tough day in his last practice (Sunday). It’ll be good to see how he bounced back today. But I was very happy with Trey and very happy with the three [quarterbacks].”

What about defensive tackle Javon Kinlaw, who increased his workload in training camp after returning from knee surgery? Will he see any action in Friday’s game?

“He’s been great,” Shanahan said. “To be able to keep pushing the reps up and down and not having any setbacks, that was great. And hopefully we can get him in that game as well (against the Packers), according to the way these next two practices are going.”
