The Patriots are adding undrafted rookie defensive tackle Scott Vallone, Aaron Wilson of the Baltimore Sun reported Wednesday.
Vallone (6-3, 275) played collegiately at Rutgers. His addition gives the Patriots nine former Scarlet Knights players on the roster, including six rookies.
The 23-year-old Vallone was a four-year starter at defensive tackle (2009-2012). He was credited with 37 tackles for loss in his career, per school statistics, including 12 as a senior.
The Patriots opened three roster spots Wednesday when they waived veteran lineman Nick McDonald, rookie receiver Perez Ashford and released receiver Lavelle Hawkins.
