The Texans have fired offensive coordinator Chris Palmer and replaced him with offensive line coach Joe Pendry, ESPN's Chris Mortensen has learned. Pendry also will work with QB David Carr. Steve Marshall takes over as offensive line coach. Marshall had been assisting Pendry. Carr, a former No. 1 overall pick by the Texans, has struggled in two games this season, throwing three interceptions and just one touchdown and has been sacked 13 times already in 2005. He has completed 25 of 47 pass attempts for 237 yards. The Texans' other top skill players on offense also are struggling as Houston has started the season 0-2 and has scored just 14 points in the two games. Top wide receiver Andre Johnson has caught just seven passes and doesn't have a touchdown in 2005, while running back Domanick Davis has rushed for just 107 yards on 29 attempts in the two losses. Pendry once worked as offensive coordinator under Dom Capers at Carolina. He was fired from that job.
