Whether it was intended for CEO Jed York or former coach Jim Tomsula is not known, but Jim Harbaugh on Sunday apparently weighed in on the latest upheaval within the 49ers organization.

Harbaugh posted the following message on his verified Twitter account just an hour after the 49ers announced the firing of Tomsula:

“Do not be deceived. You will reap what you sow.”

Shortly after the 49ers’ victory in last season’s finale, the organization announced a “mutual parting” with Harbaugh. The 49ers finished with an 8-8 record and out of the playoffs for the first time in Harbaugh's four seasons. Harbaugh had taken the 49ers to the NFC Championship game in the previous three seasons, including an appearance in the Super Bowl.
