Indianapolis Colts left guard Quenton Nelson did not participate in Thursday's practice. The team listed their two-time First Team All Pro out with a back issue on the official injury report.
Nelson was not on Wednesday's injury report, so his sudden appearance four days before the season-opener could be concerning for the Colts. Coaches were not slated to address the media Thursday, so the team didn’t shed any light on the extent of Nelson's injury.
During the first two years of his career, Nelson has been a pillar, playing and starting in 34 consecutive games (including the postseason).
