The Eagles announced yesterday that tight end L.J. Smith underwent surgery Wednesday to repair a sports hernia, the same injury that eventually ended quarterback Donovan McNabb's 2005 season. Smith, who is entering the final year of his contract, will miss the team's final full-squad minicamp, which begins Tuesday and runs through June 14. The Eagles said his condition would be evaluated over the next several weeks to determine whether he will be ready for training camp.
