ORCHARD PARK, N.Y. (AP) - A person with direct knowledge of Cordy Glenn's injury tells The Associated Press the Buffalo Bills starting left tackle's injured left foot is fine and he is expected to resume practicing next week.

The person spoke to the AP on the condition of anonymity on Friday because the Bills have not disclosed that information after Glenn missed his second straight day of practice. Coach Sean McDermott referred to Glenn's injury as "general foot soreness," and said it was too early to determine whether surgery would be required.

McDermott also revealed Glenn traveled to have his injury evaluated by foot specialist Robert Anderson in Charlotte, North Carolina on Thursday.

Glenn was held out of spring practices before being cleared for the start of training camp last week. He was practicing on a limited basis before missing his first session on Thursday.

Glenn has been a starter since his rookie season in 2012, and last year became one of the league's top-paid tackles after signing a five-year, $65 million contract extension.
