Matt Barrows of the Sacramento Bee is reporting viaGib Twitter that starting center and team captain Eric Heitmann has been waived and placed on injured reserve. That means he's done for the season and no longer counts toward the 53-man roster. It's significant for the 49ers in that many would argue Heitmann's case for being the team's best offensive lineman these past few seasons.
Heitmann had yet to appear in a game yet this regular season for San Francisco, suffering a broken fibula during the team's preseason training camp. He was carried on the roster and was expected to make a full recovery, but has had a nagging neck injury that apparently is more serious than once thought. David Baas has been taking all of the starting snaps at center for the team, and is doing a decent-to-good job on an otherwise streaky offensive line.
The 49ers recently claimed LB Thaddeus Gibson off of waivers.
