[THE UNBEATENS] Iowa, which didn't win a game in the Big Ten last fall until its season finale, remained unbeaten in 2011 with a 1-0 win over Indiana and 1-1 tie against Purdue, but the 9-0-2 Hawkeyes suffered a blow as Katie Nasenbenny, who scored the winning goal against Indiana and has been a key to the Iowa turnaround, injured her knee in the Purdue game.

Nasenbenny got tangled up with a Boilermaker player and fell awkwardly to the ground. She had to be helped off the field and returned to the sidelines using crutches.

Nasenbenny, who was scheduled to have an MRI on her knee upon returning to Iowa City, had scored five goals, including two game-winners, this season. She missed all but one game in 2010 after tearing her ACL in practice.

Freshman Cloe Lacasse leads the Hawkeyes with 10 goals and four assists. Nasenbenny and fellow sophomore Leah DeMoss are second on the team with five goals.

The win and tie left Iowa 1-0-2 after three conference games. It won all eight non-conference games.

"The first three games have been what we thought," said Iowa coach Ron Rainey. "They have all been difficult and emotional games. While our technical focus this week will be on converting chances, our effort level, mentality and intensity, all of the things we can control were what we want them to be. I'm proud of how the weekend went, but now we need to get some rest."

The Hawkeyes are home the next two weekends, hosting Michigan, Michigan State and Minnesota.
