Adams starting for Pool; Hadnot in lineup

Browns coach Eric Mangini benched free safety Brodney Pool for Sunday's game at Chicago and started Mike Adams in his place.

Pool missed a key tackle on receiver Donald Driver's 71-yard touchdown in a 31-3 loss to the Packers last week. Defensive coordinator Rob Ryan said Friday he had spent extra time with Pool working on his tackling.

Other lineup changes include Rex Hadnot for Floyd Womack at right guard, Steve Heiden for Robert Royal at tight end, David Bowens for Kaluka Maiava at inside linebacker and Jason Trusnik for Bowens at outside linebacker.

It is the first start for Hadnot since he suffered a torn MCL in his left knee on Aug. 6. He played some in relief of Womack the past two games.

Maiava, a fourth-round pick from USC, strugged in pass coverage the past two games after D'Qwell Jackson suffered a season-ending pectoral injury late in the first half at Pittsburgh. Trusnik, a Nordonia High School product acquired in the Oct. 7 trade with the Jets for Braylon Edwards, also started at Pittsburgh when Kamerion Wimbley was out with the flu.

Kicker Phil Dawson returns after missing five games with a right calf injury. His replacement, Billy Cundiff, is inactive.

Heiden has missed the past two games, presumably suffering a setback after undergoing right knee reconstruction in December.

Also inactive is Royal (hamstring, finger), tight end Greg Estandia (knee), running back Chris Jennings, offensive lineman Billy Yates and defensive backs Anthony Madison and Gerard Lawson.
