Smith, 29, signed to New England’s practice squad in December and later agreed to a futures contract after the season.
The 6-foot-1, 199-pound Ohio State product originally entered the league in the second round of the 2015 NFL draft with the New York Jets. After missing the entirety of 2017 and 2018 while working back from a second torn ACL in his right knee, Smith made stops with the Dallas Cowboys and Houston Texans.
Smith has played in 18 career games, including six starts, to total 15 receptions for 248 yards and two touchdowns.
New England’s first practice of training camp is set for Wednesday. The wideout depth chart currently stands with Jakobi Meyers, Nelson Agholor, Kendrick Bourne, N’Keal Harry, Gunner Olszewski, Marvin Hall, Devin Ross, Kristian Wilkerson, Isaiah Zuber and rookie seventh-round draft choice Tre Nixon out of Central Florida.
The Patriots hosted undrafted free agent Marlon Williams, also from UCF, for a workout on Monday.
