The San Francisco 49ers are expected to make sweeping changes, dismissing both head coach Chip Kelly and GM Trent Baalke, according to league sources.

Meetings are expected to occur as early as postgame Sunday -- San Francisco hosts the Seahawks at 4:25 p.m. ET -- and no later than Monday to determine their ultimate fates, sources said. Both Kelly and Baalke are said to know that their time in San Francisco is coming to an end.

The 49ers declined any comment.

Kelly has three seasons remaining on his contract.
