Cornerback Al Louis-Jean signs with the Ottawa Redblacks, the reigning Grey Cup champions in the Canadian Football League.

Brockton’s Al Louis-Jean is back in professional football.

The 23-year-old cornerback, who left Boston College early to turn pro in 2014, has signed a contract with the Ottawa Redblacks, the defending Grey Cup champions of the Canadian Football League.

Louis-Jean appeared in nine games as a rookie free agent with the Chicago Bears three years ago and more recently spent time with the Washington Redskins (who signed him to their practice squad during the 2015 postseason) and Miami Dolphins (who signed him to their training camp roster in 2016).

Signed by Miami last Aug. 8, Louis-Jean appeared in three preseason games and recorded three tackles prior to being released by the Dolphins at the end of that month.

Louis-Jean broke into the NFL with the Bears in 2014, appearing in nine games and registering nine tackles and one pass defensed.

Released by the Bears on Aug. 31, 2015, Louis-Jean remained out of football until Jan. 5, 2016, when the Redskins signed him to their practice squad. Subsequently signed to a futures contract by the Redskins following their playoff elimination, Louis-Jean was released by that team in May of 2016.

Louis-Jean joins a team that won the CFL’s East Division with a record of 8-9-1 last season, then topped the Edmonton Eskimos, 35-23, to advance to the league’s championship game. The 2016 Redblacks won Ottawa’s first Grey Cup in 40 years, stunning the heavily-favored Calgary Stampeders, 39-33, in overtime.
