The Chicago Bears suffered a 23-20 overtime loss to the lowly Buffalo Bills on Sunday and the news keeps getting worse.

Bears offensive linemen Roberto Garza and Matt Slauson are slated to undergo MRIs on Monday, according to Pro Football Talk's Mike Florio.

In his 14th season, Garza is the most experienced player on the Bears.

It won't get much easier for Chicago facing the 49ers in Week 2, when San Francisco will play its first regular-season game at Levi's Stadium.
