MADISON, Wis. (AP) — Wisconsin kicker Rafael Gaglianone is out for the season after undergoing surgery for a back injury.

Gaglianone missed the Badgers' 30-6 win at Michigan State last Saturday due to his injury. The team said in a statement his condition appeared to improve Sunday but then worsened so he underwent surgery Thursday. No. 8 Wisconsin plays at No. 4 Michigan on Saturday.

The junior was off to a strong start this season, converting seven of eight attempts before being sidelined. He missed spring practice in 2015 due to a similar injury.

The Badgers say that since Gaglianone played in only three games, he's eligible to apply for a medical hardship waiver from the NCAA to play an additional season.
