UPDATED: Grasu tore his right ACL, likely done for the season

UPDATE, SUNDAY, 9:30 A.M. CT: The Chicago Sun-Times is reporting that starting center Hroniss Grasu's MRI last night revealed a torn anterior cruciate ligament in the right knee. He will require surgery and will likely miss the 2016 season.

Free agent signee Ted Larsen and rookie Cody Whitehair are the favorites to replace Grasu, though if Whitehair takes over at center Larsen will likely take Whitehair's spot at left guard.

Grasu left practice on a cart Saturday following a non-contact injury. The second-year center was hurt while blocking downfield on a screen pass during the team's annual Family Fest practice at Soldier Field. The injury occurred close to the Bears sideline, giving head coach John Fox a clean view. Fox said the injury "looked fairly serious."

From ChicagoBears.com:

"I actually saw it. It was right in front of me," Fox said. "I don't know the extent of it. It looked fairly serious. But we don't really know until the medical people look at it.

"It was non-contact. He was changing direction and it didn't go well. He landed pretty funny. We'll see the extent of it as we go, but it was a non-contact injury."

The Bears won't release an official depth chart until just before the preseason opener Thursday, when they host the defending champion Denver Broncos.
