Star receiver Quintez Cephus will miss the rest of the season for No. 6 Wisconsin because of an injured right leg.
Badgers coach Paul Chryst said after practice Thursday that Cephus had surgery this week.
He leads the Badgers in receiving yards and touchdown catches. The sophomore was hurt during the 45-17 victory last week at Indiana. Cephus finishes the year with 30 catches for 501 yards and six scores.
Wisconsin also remains without senior wideout Jazz Peavy because of a right leg injury.
With Cephus and Peavy out, sophomore A.J. Taylor and freshmen Danny Davis and Kendric Pryor will take on more responsibility. All three receivers have shown promise.
The Badgers (9-0 overall, 6-0 Big Ten, No. 8 College Football Playoff) play host to No. 25 Iowa (6-3, 3-3, No. 20 CFP) on Saturday.
Who's Arkansas' QB?
Bret Bielema insists he's not keeping a secret about who will be Arkansas' quarterback against No. 24 LSU on Saturday.
The Razorbacks coach, however, is intent on letting a full week of practice play out before he decides between senior Austin Allen and freshman Cole Kelley.
