Alonzo Harris had two touchdowns, and Justin Anderson forced two of Western Kentucky’s four turnovers, helping the Ragin’ Cajuns to a 37-20 win Tuesday.

Harris finished the game with 115 yards and two touchdowns, and Elijah McGuire added 71 rushing yards.

Quarterback Terrence Broadway struggled with passing for UL (3-2, 1-0), completing only five passes for 90 yards on the night. He went the entire first quarter without a completion, making his first with 3:18 remaining in the second quarter.

Western Kentucky (4-2, 1-1) had its own quarterback issues, losing starter Brandon Doughty late in the third quarter to injury.

The Cajuns fell behind early on a 15-yard touchdown pass from Doughty to tight end Mitchell Henry.

The Cajuns’ defense came up with huge second-quarter plays to get UL in the game. The Cajuns got on the board in the second with an Al Riles interception returned for 99 yards for a touchdown. The return is the second-longest pick-six in UL history.

Anderson’s first forced turnover led to a 1-yard Harris touchdown, which tied the game at halftime.

Broadway ran in a 1-yard touchdown, and Stephen Brauchle punched in a 23-yard field goal to give the Cajuns a more comfortable 23-13 lead going into the fourth quarter.

WKU’s Antonio Andrews added a touchdown in the fourth quarter, but after a second forced turnover for Anderson and a second touchdown from Harris, the Cajuns nailed down the win.

UL finished with a total of 18 first downs and 344 offensive yards, 254 of which were rushing.

The Cajuns play another Tuesday game next week at Arkansas State. The game will be aired on ESPN2.
