The Vikings hit the field Tuesday for the first practice of the 2017 regular season. Nearly every contributor was taking part, a noticeable departure from previous seasons anchored by early injuries.

Left tackle Riley Reiff, running back Latavius Murray and receiver Laquon Treadwell — all held out for significant stretches this preseason — were suited up and looked unlimited during the first 15 minutes of practice, the only portion open to reporters during the regular season.

Two players, defensive end Brian Robison (leg) and guard Danny Isidora (undisclosed), were not practicing. Robison, who a week ago said his injured leg shouldn't keep him from playing against the Saints, was shuffling side to side in rehab drills with a Vikings athletic trainer. Isidora watched offensive linemen in individual drills with a wrap on his left leg.

But the starting lineups, which are younger on offense and defense than a year ago, remain intact six days from Monday night's opener against the Saints at U.S. Bank Stadium.

Previous seasons have told different stories. This time last year, the Vikings had just traded for quarterback Sam Bradford after Teddy Bridgewater went down in an Aug. 30 practice. Left tackle Matt Kalil was also struggling to practice through a hip injury that ultimately ended his season a few weeks later.
