The 6-foot-3 receiver was released Saturday as the Pats cut their roster to 53 players, the team announced.
The 2013 second-round pick spent the past two seasons dealing with injuries and inconsistent play that stymied his growth after a promising rookie season. Dobson had just 16 receptions and zero touchdowns in the past two years.
New England also cut wide receiver Keshawn Martin, who caught 24 balls for 269 yards in eight starts last season after arriving from Houston.
Joining Thompkins on the way out of town are two ex-general manager John Idzik draft picks: tight end Jace Amaro and cornerback Dee Milliner. Amaro, a second-round selection in 2014, has struggled to secure the starting job ever since going on IR with a shoulder injury to start the 2015 season. Milliner has also struggled with injuries, most recently with a hamstring. Both were waived on Saturday.
- Cecil Shorts III has been released by the Houston Texans. Shorts spent one season with the Texans after four with the Jaguars, catching 42 balls for 484 yards. The wideout was likely phased out of Houston's plans after the team drafted standout rookies Will Fuller and Braxton Miller. Houston also released safety Antonio Allen, who previously spent three seasons with the Jets.
- The Washington Redskins released tight end Logan Paulsen. Paulsen was entering his seventh season with the franchise and had totaled 801 yards and six touchdowns over his career. The tight end missed all of last year with a turf toe issue. Washington also parted ways with defensive tackle Cullen Jenkins, whom the Redskinssigned Monday.
- The Indianapolis Colts released running back Stevan Ridley less than one week after signing him, the team announced. The former Patriots and Jets running back, who has been hampered by an ACL injury, was cut by the Lions last week. Indy also released veteran linebacker Nate Irving. Irving started two games in one season with the Colts after spending four years in Denver.
