With the end of non-league play, Ivy League competition is just starting to kick in.

While Harvard remains at the top of the conference, Princeton and Penn both remain undefeated in conference play and hope to make a run at the title.

Here are the Week 6 matchup previews.

Penn (2-3, 2-0) vs. Yale (1-4, 0-2), Saturday 12:00 ET

While Penn hopes to extend its conference winning streak, the Bulldogs hope to turn their season completely around. Yale has been on a dreadful four-game losing streak that has really put them at the bottom of the Ivy League. Tyler Varga will have to have a career game if the Bulldogs intend to pull off an upset over the visiting Quakers.

Cornell (3-2, 1-1) vs. Brown (3-2, 0-2), Saturday 12:30 ET

Despite Brown's strength as a contending squad, the team sits at 0-2 in conference play, having fallen to both Harvard and Princeton. Cornell desperately needs the return of Jeff Mathews if it hopes to still make a run at the Ivy League title. This will definitely be a heated matchup this week, one that has the makings of an offensive shootout.

Harvard (5-0, 2-0) vs. Princeton (3-2, 2-0), Saturday 1:00 ET

If anyone had said that this matchup was actually going to be a quality contest at the beginning of the season, most college football fans would have laughed. But now, this game has the makings of another huge conference game, as Harvard intends to continue its undefeated route to another Ivy League crown. Princeton hopes the home crowd and a three-game winning streak will help put it over the edge.

Dartmouth (3-2, 1-1) vs. Columbia (1-4, 0-2), Saturday 1:30 ET

Columbia almost upset Penn last weekend, and the Lions intend to come out with a win over Dartmouth this weekend. The Big Green have been brutally exposed for their dependency on the run, and the Lions will have to adjust to stop it. If they can do that, this game will be completely up for grabs. The Big Green hope they can earn a second conference win of the season, coming off of a poor performance against Sacred Heart.
