Buckeyes' Boren to miss several weeks

Ohio State offensive lineman Justin Boren sustained a sprained knee during practice Friday and will miss several weeks, a source told ESPN affiliate Web site Bucknuts.com.

Boren, projected to be Ohio State's starting left guard, is expected to miss no more than three weeks with a sprained MCL, the source said. Ohio State was unable to confirm the injury.

Boren made national headlines when he transferred to Ohio State from archrival Michigan and criticized Wolverines coach Rich Rodriguez. He earned honorable mention All-Big Ten honors with Michigan in 2007 and made a strong impression at Ohio State during spring practice.

Junior Connor Smith likely will slide into Boren's spot during his absence.
