Means injured his hamstring during Saturday's 34-0 preseason loss to the Rams, Matthew Paras of The New Orleans Times-Picayune reports.
Means went to the blue medical tent during Saturday's game and did not return, finishing with one catch on four targets for five yards. He'll undergo further tests to determine the severity of the injury, but it puts him in jeopardy of missing the Saints' preseason finale against the Cowboys on Friday.
