Purdue announced yesterday that QB Rob Henry tore the anterior cruciate ligament in his right knee during practice Tuesday in West Lafayette, Ind.

School officials did not say how much time they expect Henry to miss pending more tests.

Just last fall, Henry took over the offense when starting quarterback Robert Marve tore the ACL in his left knee. Henry was listed as the No. 1 quarterback on the depth chart since practice opened earlier this month.

“Rob Henry is a huge part of our football program, our heart goes out to him,’’ coach Danny Hope said in a statement.

His absence could open the door for Marve, the transfer from Miami, to reclaim the starting job. But it’s unclear whether Marve is 100 percent just yet.
