The Boilermakers took a lead at Marshall into the fourth quarter but allowed two touchdowns in the final five minutes and lost to the Thundering Herd 41-31 on Sunday.
Lang returned an interception 30 yards for a touchdown on the initial play from scrimmage, and his 55-yard return of a pick for a score with 1:20 left in the match maintained Marshall’s triumph.
“What a player. He’s got ‘it,'” said Marshall coach Doc Holliday.
In between, Lang was active, also, creating a team-high 17 tackles as Marshall avoided another home loss to a team from an important conference.
After Devon Johnson put Marshall ahead 34-31 with a 6-yard scoring run with 2:50 staying, Purdue had lots of time left.
Marshall quarterback Michael Birdsong had an up and down debut in his first match since transferring from James Madison this past year.
He appeared shaky at times before a sellout home crowd and Marshall’s offense misfired when it’d chances to scores.
Birdsong threw behind Nick Mathews inside Purdue’s 10 late in the third quarter and Marshall settled for a field goal.
Johnson had a 20-yard scoring run for Marshall in the first quarter but was quiet for most of the match, something he was not accustomed to last year when he ran for 1,767 yards.
