Source: WR Schilens in for tryout

FOXBOROUGH, Mass. -- NFL teams are permitted to invite players to attend their minicamps on a tryout basis, and five players who were not listed on the Patriots roster were spotted Tuesday on the practice fields at Gillette Stadium.

One of those players, wearing number 84, was wide receiver Chaz Schilens, a league source told ESPNBoston.com.

Schilens spent the 2012 season with the New York Jets. The 6-foot-4, 225 pound wideout was drafted by the Raiders in the seventh round in 2008 after a productive college career at San Diego State. He spent four seasons in Oakland and played in 44 games before being picked up by the Jets last offseason.

Schilens has career totals of 100 catches for 1,191 yards and two touchdowns.
