UPDATE (3:05 p.m. ET): The Green Bay Packers’ worst fears have been realized.

Aaron Rodgers suffered a broken collarbone Sunday against the Minnesota Vikings and could miss the rest of the season.

UPDATE (2:40 p.m.): The first update on Aaron Rodgers is… not good.

The Green Bay Packers are worried their star quarterback suffered a broken collarbone, FOX Sports’ Jay Glazer reported Sunday.

ORIGINAL STORY: Hold your breaths, Green Bay Packers fans.

Packers star quarterback Aaron Rodgers exited Sunday’s game against the Minnesota Vikings early in the first quarter, sending Packers fans and fantasy football owners into panic mode.

Vikings linebacker Anthony Barr delivered a big hit on Rodgers, who appeared to land hard on his right shoulder.

The Packers quarterback walked off under his own power but was carted to the locker room to be evaluated. He was diagnosed with a right shoulder injury and ruled as questionable to return.

Losing Rodgers for any period of time obviously would be a tough blow for Green Bay, as backup Brett Hundley has attempted just 11 passes during his two years-plus seasons in the NFL.

Stay tuned for more updates.
