WEST LAFAYETTE, Ind. (AP) - Purdue's Caleb TerBush threw four touchdown passes Saturday and the Boilermakers ran two interceptions back for scores as they held off Marshall 51-41.

TerBush finished 27 of 37 for 294 yards on a day both offenses had big numbers.

Marshall (2-3) lived up to its billing as the nation's No. 1 passing offense.

After forging a 14-14 tie early in the second quarter, Purdue's defense flipped the game by turning three quick interceptions into touchdowns. Cornerbacks Ricardo Allen and Josh Johnson each scored on their interceptions, marking the first time in Purdue history that two interceptions were returned for TDs in the same game. When the flurry ended, Purdue (3-1) led 42-14.

Marshall charged back in the second half, closing the gap to 10 with 3:46 to play but couldn't get any closer.

Tommy Shuler set Marshall's single-game record with 19 receptions and finished with 200 yards.
