Ian Williams has broken ankle


It didn’t look good when it happened.  And it isn’t good.

Per a league source, 49ers defensive lineman Ian Williams suffered a broken ankle when he was blocked low during the first quarter of Sunday night’s game between San Francisco and Seattle.

It was a legal block, but as NBC’s Cris Collinsworth said at the time, it shouldn’t be.

Williams has been replaced by Glenn Dorsey, a former top-five pick who joined the 49ers as a free agent in the offseason.
