Yes, the uruk can shield if charged the turn following being knocked down. So long as you can still roll to win a fight, you can opt to use the shielding rule and gain double your normal rolls but get no rolls for wounding. Since you can't strike blows when prone anyways, it is a great tactical decision. Also, the rules for shielding in the MoM rulebook say that you are able to shield after being knocked to the ground. However, you still have to survive long enough to win priority in order to get up.

Ummm, actually you still roll dice to win the fight. You just can't roll to wound the attacker.
