Steelers' Allen undergoes minor knee surgery
• Steelers cornerback Cortez Allen had minor surgery on his right knee Friday that will keep him off the field for at least a couple of weeks. “We wanted him to get the surgery done now so he can begin rehabilitating immediately,” coach Mike Tomlin said. “This surgery was a minor procedure and will have no long-term effects on his return to the field. We look forward to his rehabilitation process and having him back on the field in a couple of weeks.” Allen has missed the majority of the first week of training camp with the knee injury. Allen, in his third year out of The Citadel, made free agent Keenan Lewis expendable following last year. Allen (6-1, 197) was selected in the fourth round of the 2011 draft. He played in 15 games as a rookie mostly on special teams. Last year, Allen played in 15 games and started three and finished with 38 tackles, two interceptions and three forced fumbles while playing in the nickel package. Veteran William Gay will take over the starting cornerback position until Allen returns.
