The Washington Redskins traded receiver Taylor Jacobs to the San Francisco 49ers for cornerback Mike Rumph -- a swap of oft-injured former high-round draft picks. Rumph was a first-round selection from the University of Miami in 2002, but he missed most of 2004 with a broken arm and played in only three games in 2005 because of a foot injury. Rumph was moved to safety last year, but the Redskins plan to use him to add depth at cornerback. Cornerback Shawn Springs saw a specialist for a sore hip, and nickel back Kenny Wright allowed two big plays and committed a pass-interference penalty in a 19-3 preseason loss Aug. 13 at Cincinnati. Jacobs has been a disappointment since the Redskins drafted him in the second round of the 2003 draft. He had a bruised pancreas during his rookie season, a strained abdominal muscle in 2004 and a sprained big left toe last year. He has been ineffective when he did play, catching only 30 passes for 315 yards in 38 games. "I wished it had worked out better for him here," coach Joe Gibbs said. "It didn't." Jacobs has a groin injury and was a longshot to make the roster in a receiving corps that includes Santana Moss, Brandon Lloyd and Antwaan Randle El.
