The Eagles placed center Jamaal Jackson on the injured reserve list on Tuesday and promoted Dallas Reynolds from the practice squad to the 53-man active roster just in time for the game against Dallas.
Jackson tore the ACL in his knee during the first quarter of Sunday's 30-27 win over the Denver Broncos. Jackson has been the starter at center since the middle of the 2005 season. This Sunday, Jackson's streak of starting in 71 straight regular season games, the fourth longest active streak in the league, will come to an end.
Nick Cole will start at center in Jackson's absence. According to head coach Andy Reid, either Max Jean-Gilles or Stacy Andrews will take Cole's spot at the right guard position.
Reynolds was originally signed by the Eagles as a rookie free agent out of Brigham Young. He worked in at guard and center during the preseason before being released. He was signed to the Eagles' practice squad on Oct. 21.
Taking Reynolds' place on the practice squad is safety Brandon Harrison. First signed by the Colts as a rookie free agent out of Michigan, the Eagles signed Harrison on Aug. 18 and released him prior to the start of the season. The 5-9, 197-pound Harrison had 69 tackles, three interceptions and three sacks during his collegiate career.
