The New England Patriots placed offensive tackle Nick Kaczur on season-ending injured reserve Tuesday, the team announced.
Kaczur suffered a serious back injury during the second day of training camp and never rejoined the team. He underwent back surgery in August.
Kaczur has started 62 of 68 regular-season games during his NFL career and also has started seven career playoff games. The Patriots drafted Kaczur in the third round in 2005 from Toledo.
