The Browns signed defensive back Tigie Sankoh after the London native was assigned to the club through the NFLís International Player Development program.

The team announced the transaction Monday along with its signing of undrafted rookie quarterback Brogan Roback, a move the Beacon Journal/ reported last week.

Sankoh, 5-foot-11 and 214 pounds, played football as a teenager and then attended the American Football Academy at Filton College in Bristol, England. He played for the London Warriors in the British American Football League.

The international development program was launched in 2017 to provide players from other countries opportunities to make an NFL roster.

Sankoh will not count against the 90-man roster limit until final cut down.

The Browns and the other AFC North teams will carry a player from overseas on their rosters until the end of training camp this summer, whereupon those in the program would be eligible for an international player practice squad exemption. The Browns, Baltimore Ravens, Cincinnati Bengals and Pittsburgh Steelers will each be given the exemption for an 11th practice squad member who would be ineligible to be activated during the upcoming regular season. Practice squads are normally composed of 10 players.
