The Saints placed Tipton (groin) on the active/PUP list Tuesday, Katherine Terrell of ESPN.com reports.
Tipton suffered a groin injury in January and is likely still suffering from the same issue. The kick and punt returner does not have a return timeline at this point, so it is unclear if he will be able to participate in training camp. If the wide receiver cannot return soon, other skill-position players will have the chance to make their case as better depth players capable of producing on special teams, and Tipton may lose his roster spot.
