Marko looked like he hurt his back several games ago and appeared to be in a lot of pain. Somebody said both he and Corey are battling injuries, which might explain their limited playing time lately.
Yeah - Masonfanatic and I both think Marko is hurt with the back injury. MF mentioned that he believes he hurt it in the Penn game. Not sure what Corey's injury is, but maybe it is that "turf toe" he struggled with last year?
