Welcome to the NFL, Chase Claypool.
With 6:34 to go in the first half, Steelers quarterback Ben Roethlisberger connected with Claypool for an 84-yard touchdown strike, which put Pittsburgh up 14-3 over the Broncos.
It was the longest play from scrimmage by a Canadian-born player, according to NFL Research.
Claypool finished the game with three receptions for 88 yards and the one score.
During his senior season with the Fighting Irish, Claypool had 66 catches for 1,037 receiving yards and 13 touchdowns in 13 games.
Claypool, along with fellow Steelers wide receivers JuJu Smith-Schuster, Diontae Johnson, and James Washington, are viable options for Roethlisberger in his comeback year after suffering a season-ending elbow injury last season.
