INDIANAPOLIS, Ind. – Ryan Kelly, the anchor of the Indianapolis Colts’ offensive line, is expected to miss a few weeks after suffering a foot injury during Thursday’s joint practice with the Detroit Lions, a source with knowledge of the situation told CBS4/FOX59. The injury isn’t expected to keep the team’s starting center out of the Sept. 10 regular-season opener against the Los Angeles Rams. The source indicated Kelly was lucky the injury wasn’t more severe.
