Newly acquired Oakland Raiders quarterback Carson Palmer, who hasn't played or practiced since last season, is expected to start Sunday's game against Kansas City, a team official told ESPN NFL Insider Adam Schefter.

Palmer shared first-team snaps Wednesday with Kyle Boller, who has been with the Raiders the past two seasons and has a big advantage in terms of knowledge of the offense and chemistry with the receivers.

But Palmer has the stronger pedigree and was acquired at a high price, meaning the Raiders will give him every possible chance to get that starting job.

"It's one day," coach Hue Jackson said. "I'm not in a rush. I don't have to rush that decision. I'm going to take my time and see where they are and see how fast he picks up the system, see how fast he gets in line with his teammates and we'll kind of go from there."

It's been a whirlwind few days for Palmer, who was a retired player in Southern California on Monday. That changed Tuesday when Oakland got Palmer from Cincinnati, shipping a 2012 first-round pick and a second-rounder in 2013 that could become a first-round selection if the Raiders make it to the AFC title game this season.

Palmer had to pass a physical, meet his new teammates, start learning the playbook and then start shaking off the rust in his first practice since the end of last season.

"There's definitely a learning curve involved for sure and I noticed that right off the bat," Palmer said. "But it was exciting. It was fun to be playing football, it was fun to be in a huddle again, it was fun to be throwing routes in 7 on 7 and teams and all these things. But I definitely have my work cut out for me as far as getting the verbiage down, especially when it comes to playing the quarterback position."

Palmer retired during the offseason rather than return to the Bengals. Cincinnati had refused to trade him but finally relented Tuesday when the Raiders made their big offer after Jason Campbell broke his collarbone.

Jackson said he had some concerns about starting a player at quarterback after only three practices with the team but that won't necessarily stop him from doing it.

"I kind of like it like that," Jackson said. "I think he kind of likes it like that. I think we all do. But we'll make the right decision for this football team. We've got a game to win, and that's the most important thing. Whatever I think is going to help us win this football game that's what I'm going to do."

Palmer's new teammates are excited to have him on board, many of them having watched or competed against Palmer over the years.
