Bears coach John Fox informed the media on Monday that guard Eric Kush suffered a torn hamstring at Saturday’s scrimmage and will undergo season-ending surgery.

The four year veteran was dealing with hamstring issues last week but the tear came in “a total different part” from the prior discomfort said Fox on Monday.

This is obviously a major blow to the Bears offensive line depth. Kush saw playing time last season when Kyle Long and Josh Sitton went down with injury. And after doing a pretty good job, the Bears signed him to a two-year, $2.7M contract this offseason.

“We feel like we have some depth at that position [guard], and we worked on that today,”Fox said after Monday’s practice.

The Bears worked Cody Whitehair at left guard and Hroniss Grasu at center with the first team offense during Monday’s full pad practice. Grasu, who is coming off an ACL injury, looks to have a roster spot locked up given Kush’s injury.

And with Long still out recovering  from ankle surgery, I expect Whitehair at LG and Grasu at C for practice and the preseason, which kicks off Thursday vs. Denver at Soldier Field.
