Joey Porter reportedly underwent arthroscopic knee surgery recently and will be out for the remainder of training camp and the preseason.
Porter should be back in time for Week 1, but this is a major concern considering his age and already declining play. If Pprter misses regular-season action, the Dolphins would likely be forced to turn to Akbar Gbaja-Biamila. The ‘Fins have poor depth at outside linebacker in their 3-4.
