Though it still appears as if the back injury suffered by Eagles wide receiver DeSean Jackson isn’t overly serious, the gifted playmaker was held out of practices at training camp in Lehigh for the second straight day. The Eagles are banking on Jackson following up his stellar 2009 season and helping the team make the transition from Donovan McNabb to Kevin Kolb. The more time the two can spend working together this camp and preseason, the better. So here’s to hoping that Jackson, who became the first player in NFL history to be nominated to the Pro Bowl at two different positions, is back on the practice field sooner rather than later.
