HC Matt Eberflus told the media that Kramer has a lower leg injury and there's no timetable for his return. However, according to Brad Biggs, the Bears are concerned that Kramer suffered a Lisfranc injury, which would most likely end his season.
This would be brutal news for the hometown kid, who made a solid impression during the spring and summer.
The Bears are already very thin at Center since Lucas Patrick went down a few weeks ago. He should, however, be back by week 1. Sam Mustipher should be the one running with the first team until Patrick gets back.
