Coach Matt Rhule said Monday that he believes Marshall (foot) is dealing with a short-term injury, Darin Gantt of the Panthers' official site reports.
Marshall was placed on injured reserve with a foot injury for the regular-season finale, but he's expected to be ready to participate in OTAs this spring. Once the 21-year-old returns to full health, he'll work on carving out a larger role after he caught just 17 of 30 targets for 138 yards during his rookie season.
