This, from the Idaho Statesman:
Boise State senior linebacker David Shields will have another shoulder surgery this month and miss spring ball, Petersen said. It's unclear when Shields, who has started for parts of the past two seasons, will be ready to play. This news appeared at the bottom of the recruiting story in yesterday's paper. It is interesting that there are so many good linebacker recruits in this class. Perhaps the team is expecting Shields to have a slow recovery.
