The Atlanta Falcons have announced that veteran tight end Justin Peelle will be sidelined for four to six weeks after undergoing surgery to repair a sports hernia.

The Falcons also practiced today without cornerback Dunta Robinson and linebacker Sean Weatherspoon. Weatherspoon will not play Sunday against the Cincinnati Bengals as he heals from a knee injury.

Robinson suffered a concussion on the play in which he delivered a concussion to Philadelphia Eagles wide receiver DeSean Jackson. He will need to be cleared by team and independent physicians before he will be cleared for a return.

Peelle’s absence will put undrafted rookie Michael Palmer in place to be Tony Gonzalez’s backup in the offense.
