Columbia (2-1, 1-0), which was winless in the Ivy League last year, shocked struggling Princeton (0-3, 0-1) with a 20-point comeback on Saturday.

Meanwhile, the Ivy League elite continued to surprise non-league teams this weekend. One week after then-ranked No. 21 University of Pennsylvania (3-0, 1-0) upset then-ranked No. 19 Lehigh, unranked Harvard (3-0, 1-0 Ivy) surprised Division I-AA powerhouse No.10 Northeastern.

Columbia 33, Princeton 27

The last time Columbia won at Princeton, NYU was in the NCAA basketball title game, the Chicago Cubs were in the World Series and the nation had just seen the end of World War II.

But on Saturday, the Lions gained long-awaited retribution, triumphing over the Tigers on the road.

At first, it looked as if Princeton was going to continue its post-World War II dominance over Columbia.

After being held scoreless in the first half of its previous two games, the Tigers leaped out to a 20-0 first quarter lead. Junior quarterback Matt Verbit, who completed 14 of 23 passes for 212 yards overall, led the charge.

Columbia kicker Nick Rudd led the Lion comeback charge in the second quarter with the first of his four field goals. Senior running back Ayo Oluwole followed with a two-yard touchdown.

With 8:50 left in the fourth quarter, junior Columbia quarterback Jeff Otis, who completed 22 of 38 passes for 326 yards on the day, scored on a one-yard run, giving the Lions their first lead; a two-point conversion brought the score to 27-20.

The Tigers tied the score with off a one-yard junior running back Branden Benson scored on a one-yard run, tying the game at 27.

With 20 seconds left in the game and ball on their own 33, the Lions only needed two play to get the ball to the Princeton 49.

After a time-out, Otis launched the ball from midfield into the end zone hitting a mobbed wide receiver Wade Fletcher with no time left on the clock.

Harvard 28, Northeastern 20

After amassing nine touchdowns in the first two Crimson victories, junior quarterback Ryan Fitzpatrick added four more against nationally ranked Northeastern.

Fitzpatrick, who completed 13 of 22 passes for 244 yards and ran for a game-high 93 yards and scored two passing touchdowns and two rushing touchdowns.

Five plays after Northeastern turnover the opening kickoff, Fitzpatrick dove into the Husky end zone on a three-yard run. Another Fitzpatrick rush on Harvard’s ensuing drive extended the Crimson lead to 14-3.

Harvard rookie receiver Brian Edwards gave Harvard a surprising halftime lead of 21-3 with the first of his two touchdown catches.

Down 28-6 with 1:28 in the third quarter, the Huskies refused to give in. Northeastern scored twice to get within eight, 28-20. But Huskies signal-caller Shawn Brady, who completed 19 of 47 passes for 241 yards on the day, could not finish the comeback.

Pennsylvania 33, Dartmouth 20

The Quakers, who went undefeated en route to the Ivy League title last year, opened their Ancient Eight play Saturday with a 33-20 victory over the winless Big Green (0-3, 0-1) in Hanover, N.H.

Behind senior quarterback Mike Mitchell, who completed 25 of 36 passes for 285 yards and two touchdowns in the first half alone, the Quakers built a 19-0 advantage at the intermission. Mitchell was removed from the game with a leg injury in the second half.

The Big Green scored on a three-yard run to open the second half, but, never managed to cut the lead to single digits.

The closest that Dartmouth got was 26-13 after sophomore Dartmouth quarterback Charlie Rittgers, who completed 28 of 48 passes for 277 yards on the day, threw for the first of the Big Green’s two touchdown passes of the game.

Rittger’s second touchdown pass came with less than three minutes remaining in the contest, after the Quakers were well on their way to their ninth consecutive victory.

Colgate 27, Cornell 24

No. 19 Colgate had seven more first downs than Cornell (1-2), outgained the Big Red by more than 150 yards, and controlled the ball for almost 17 more minutes. But in the end, it took a last second field goal to secure the Raider victory.

Colgate kicker Lane Schwarzberg nailed a 22-yarder as time expired to give Colgate the 27-24 victory.

Colgate scored 24 unanswered first half points to take the lead 24-7 at intermission. But, Cornell rallied. Senior quarterback Mike Razzano, who completed 14-of-25 passes for 171 yards on the day, threw a 15-yard touchdown pass to Anthony Jackson after the break and Sean Nassoiy brought the Big Red within three on a 38-yard fumble recovery.

URI 27, Brown 9

For the third consecutive time in the last three seasons, Brown (1-2) failed to surpass its intrastate rival.

Brown gave up three interceptions and three fumbles, enabling the University of Rhode Island to rout the Bears in Providence, R.I.

After a Bears fumble less than 15 seconds into the game, Rhode Island running back Luther Green scored on an 18-yard run.

Later in the first quarter, Rams kicker Shane Laisle tied the 29-year old URI school record with a 50-yard field goal.

The Rams were up 20-2 at the half.

With 5:30 remaining in the game, senior Brown quarterback Kyle Slager, who went 37 of 54 for 357 yards in the game, completed his lone touchdown pass.
