But the Penn State commit’s showcase experience was cut short this morning when he pulled up with a strained right hamstring during his 40-yard dash.

McLean, who has taken part in intense conditioning workouts with his Cougars teammates this summer, said he felt fine in warmups and stretched Tuesday night and Wednesday morning with no tenderness in his hamstring. The run came ahead of his initial SPARQ testing.

“It was my time up for the 40-yard dash and I had just watched a couple guys run before me,” McLean said. “I got to about 30 yards and then I pulled up.”

The injury ended his playing time at The Opening, and McLean said he expects to be sidelined for 4-5 weeks. He said the injury was a pull, and not a more serious tear.

“It sucks to travel all this way and have this happen,” McLean said. “But I’m just going to enjoy my time here. It’s all about the experience, and I’m excited to have made it this far.”

McLean expects to be back in time for Quince Orchard’s regular season opener against Clarksburg on Sept. 5, but the All-Met lineman said he will not rush back if he isn’t 100 percent.

“I’ll try to get back as quick as I can, but I can’t make the injury worse than it is,” McLean said. “I’m going to be smart about it, heal up completely and start fresh.”
