At this point, I won't speculate on what will happen with Ahmad Brooks.
However, Parys Haralson would be in a position to benefit from Brooks' potential absence in training camp and/or the regular season.
The 29-year-old outside linebacker took a pay cut this offseason to stay with the Niners. He's in the last year of his deal, which means he'll need to have a productive season if he wants to earn another NFL contract.
Even if Brooks starts from Week 1, Haralson could be a vital reserve as the top outside linebacker off the bench. However, he'll be battling younger players for playing time, including promising third-round pick Corey Lemonier.
If Haralson, who missed the 2012 season with an arm injury, looks a step slow in training camp, he could fall to the bottom of the depth chart fast.
