Marshall failed to come up with either of his two targets in the Panthers' 17-3 preseason loss to the Patriots on Thursday.
Marshall came up empty after impressing in training camp practices, but the Panthers rolled out undrafted rookie Jack Plummer as the starting quarterback Thursday. Marshall got extra opportunity Thursday with Diontae Johnson, Adam Thielen and Xavier Legette (foot) sitting out, and the fourth-year wideout will look to continue making his bid for a roster spot during Carolina's second preseason game against the Jets on Aug. 17.
