SANTA CLARA, Calif. (AP) — Jim Harbaugh won't say whether he has spoken to San Francisco 49ers CEO Jed York since the owner took to Twitter on Thursday night about a performance that "wasn't acceptable," or if they have even recently discussed his coaching future with the franchise.

He would say they hadn't talked about his employment status during the weekend. San Francisco's 19-3 loss to the Seahawks on Thanksgiving and the ugly aftermath was still plenty fresh four days later.

"Nobody that's for us was happy about losing the game, losing a big game," Harbaugh said. "We're still not happy about it. Our job is, my job, let's talk about my job. My job is to get it right. That's what we're attacking today, without excuse. Onward to the Raiders."

Harbaugh also said Monday that offensive coordinator Greg Roman will remain the play-caller and said he has "unwavering support for all our coaches and our players."

Harbaugh said neither management nor ownership has asked him to make any changes on the staff. General manager Trent Baalke's daughter, Cassie, posted on her now-defunct Twitter account late Thursday: "Greg Roman can take a hike..the 49ers don't want you no more." Her words were accompanied by an image of hands clapping.

Trent Baalke issued a statement Friday that they both had apologized to Roman for the "unfortunate matter."

Baalke watched the beginning of Monday afternoon's practice, even leaning over with hands on knees as the linebackers went through their individual drills.

When pushed about whether he and York have at least addressed the public comments or concerns about the game, Harbaugh responded: "To me, that's not significant. What's significant is we move on without excuse and get it right, make it right. That's our jobs."

Harbaugh declined to acknowledge whether he even wants to return in 2015 for the final year of his $25 million, five-year contract, instead turning to what became his regular response Monday: "What I want is to attack this week and get it right."

At least a few players said Monday they agreed with York's assessment.

"We felt that way before he tweeted that," fullback Bruce Miller said. "A very prideful group here, as a team, as an offense we want to perform better, whatever that takes."

Colin Kaepernick went 16 for 29 for 121 yards with two interceptions and four sacks in one of his worst outings as a pro and the 49ers were outgained 379-164. Kaepernick's 36.7 passer rating was the second lowest of his career.

San Francisco (7-5) is back to work after the humiliating loss that put its playoff hopes in serious jeopardy.

"No drastic measures need to happen," tight end Vance McDonald said. "We have the players to get it done, we know we can get it done. It's just, you kind of get lost every now and then. No doubt we have the coaches and the staff to get it done. We're going to get our heads back where they need to be."

Next up is a short road game against the one-win Raiders (1-11) in Oakland on Sunday. Harbaugh was so curt he wasn't even in the mood to reflect on what he learned during his early coaching days with the Raiders under late owner Al Davis, noting that time is already "well-documented."

In terms of adding any new wrinkles to the offense, Harbaugh said that could happen but "not going to explain."

He is trying to remain focused on getting through each week with the playoffs still within reach. San Francisco goes to Seattle next week before playing its final two games at home, against San Diego and Arizona.

"I don't worry about my future," Harbaugh said. "Haven't participated in any of that speculation. I think I have a recessive gene for worrying about my own future."

Notes: LB NaVorro Bowman will continue to rehab his surgically repaired left knee rather than practice this week. The 49ers must decide whether to activate him or place him on season-ending injured reserve by Dec. 9. ... CB Chris Culliver and RB Carlos Hyde each wore non-contact blue jerseys, but it wasn't clear what their injury concerns were.
