Saints receiver Horn still bothered by injury

Four-time Pro Bowl receiver Joe Horn sat out significant portions of the New Orleans Saints’ practice Tuesday, still bothered by the groin injury that caused him to miss the last four games of the regular season.

Saints Coach Sean Payton said Horn, who had two touchdown catches in the victory over Philadelphia earlier this season, is questionable for the rematch Saturday night in the second round of the NFC playoffs. The Saints also re-signed kickoff specialist Billy Cundiff for the playoffs.
