Panthers put Otah on injured reserve

The Carolina Panthers have placed offensive tackle Jeff Otah on injured reserve and signed offensive lineman Rob Petitti to take his place.

Otah tore the meniscus in his left knee Sunday against the New England Patriots and becomes the 10th player to be lost for the season.

General manager Marty Hurney says Otah will undergo surgery. His loss means Carolina will be without both starting tackles from the start of the season. Jordan Gross broke his leg last month.

Inexperienced Geoff Schwartz will likely start at right tackle on Sunday against the Minnesota Vikings.

Petitti previously played for the Dallas Cowboys, St. Louis Rams and New Orleans Saints.
