The discontent in San Francisco is growing fast.
Following an embarassing loss to the San Francisco 49ers on Thanksgiving night, 49ers owner Jed York chimed in via Twitter.
"This performance wasn't acceptable," York wrote. "I apologize for that."
Ouch.
This, along with reports about York and general manager Trent Baalke clashing with Harbaugh, is sure to fan speculation about Harbaugh's future.
Perhaps he'll wind up coaching the 49ers' next opponent next season: the Oakland Raiders.
Meanwhile, Baalke's daughter, Cass Baalke, a college freshman wrote on Twitter before deleting the message: "Greg Roman can take a hike..the 49ers don't want you no more ????????"
