"I have been walking around yesterday and today," Styperek said. "I am going to rest this weekend, but I may be back for the matches against Brown and Yale next weekend."

With Styperek down, the team will probably look to pair Passarella with another equally successful partner.

The Crimson last faced the Tigers from central Jersey in the semi-finals of the ECAC championships at Princeton last October. Harvard prevailed, 5-2.

Princeton should be the Crimson's toughest league opponent in its search for another Ivy crown. Princeton is currently ranked No. 67 in the nation, though its line-up features no ranked players.

Although Penn jumped out to a quick start in its non-league season, the Quakers have slowed a bit in league play. The team lost to Princeton 6-1 and Yale 5-2 in the last couple of weeks.

This will be the first meeting of the Quakers and the Crimson this season.

The Crimson will face Princeton at 2 p.m. tomorrow and Penn at noon on Saturday.
