There’s a ton of hype building for Adam Trautman at New Orleans Saints training camp, but the rest of the tight ends depth chart is starting to look a little shaky. Backup Ethan Wolf, who took former draft pick Tommy Stevens’ spot on the practice squad last season, is expected to miss a week a more with an ankle injury, per NewOrleans.Football’s Nick Underhill. Veteran pickup Nick Vannett was signed to help replace Josh Hill as the co-starter with Trautman (stepping in for Jared Cook), but he’s missed a few practice sessions without explanation. That leaves New Orleans with just three healthy tight ends available.
