Madden NFL 07

I can't seem to unlock LaDainian Tomlinson's madden card. It has a trophy on it and when i click on the card it says "To unlock this Madden Card, you must get gold in the All-Madden Ground Attack drill." But the player in that drill is Shaun Alexander and whenever i beat it and get gold on the all-madden drill it says that i have unlocked Shaun Alexander's card and it shows in my madden card book that i have that card.

I was just wondering if anyone else had this problem or could help me out?

thanks
