UW senior linebacker Jonathan Casillas, who has been out the last couple weeks with an ankle injury, thought his teammates could use a lift.

  So, Casillas returned to the field on Thursday night, in the final practice before Saturday's spring game.

  Casillas only took part in pre-practice work and some individual drills, but his presence always lifts the spirits of the defense.

  "I came back today, just to kind of get back in the flow," Casillas said. "Just talking to some of the guys, let them feed off me, because I think I bring a little more energy than the average Wisconsin player."

  UW coach Bret Bielema also said there's a chance sophomore receiver Kyle Jefferson, who missed his second practice after suffering a gash on his leg that required stitches, after running down a hall and running into a wall, will be available for the spring game.

  On the field, senior quarterback Allan Evridge, who has picked things up noticeably in the last three practices, going back to last Saturday's scrimmage, made one of his best throws of the spring.

  Evridge threaded the needle perfectly in a tight space, splitting defenders Mario Goins and Jay Valai, on a pass to tight end Lance Kendricks in the right corner of the end zone.

  Sophomore Isaac Anderson also continued to look like one of the top two receivers on the team, along with sophomore David Gilreath. Anderson beat cornerback Otis Merrill with a diving grab on a throw from Scott Tolzien for the best catch of the practice. Anderson also had not one, but two nice grabs in traffic in the back of the end zone in a red-zone drill.
