ROSEMONT, Ill. (AP) -- Russ Michna passed for 300 yards and five touchdowns, including a 14-yarder to Damian Harrell with 1:32 left in the fourth quarter, and the Chicago Rush defeated the Grand Rapids Rampage 55-52 on Sunday.

After Michna and Harrell combined to put the Rush (6-2) ahead, Chicago's defense came up with a game-saving stop.

On fourth-and-5 from the Rush 20, Grand Rapids (2-5) passed on a potential game-tying field goal and went for the win.

James McPherson launched a pass into the end zone toward Anthony Hines, but Dennison Robinson knocked the ball away.

McPherson finished with 272 yards and six touchdown passes, three to Kenny Higgins.

Donovan Morgan had 10 receptions for 149 yards and four touchdowns for the Rush.
