Britons Menelik Watson and Jack Crawford have both signed for new NFL teams during the first few days of free agency.
Offensive tackle Watson, who was born in Manchester, has joined the Denver Broncos having spent his first four years in the league with AFC West rivals, the Oakland Raiders.
Watson has battled injuries throughout his time in the professional ranks but has a better chance to be a regular starter along Denver's offensive line.
Londoner Crawford was also a free agent following a stint with the Dallas Cowboys and the 28-year-old defensive lineman has joined the Atlanta Falcons.
Last month the Falcons were in the Super Bowl but squandered a 25-point lead to the New England Patriots.
The number of British-born players in the NFL will be increased following next month's draft when safety Obi Melifonwu and offensive lineman Jermaine Eluemunor are expected to be selected in the early-to-mid rounds.
