Jets quarterback Antonio Allen was diagnosed with a concussion Friday, after taking a hit to the head during Friday's preseason game against the Giants. Allen will have to go through the league's concussion protocol before he can be cleared to play, and seems unlikely to return in time for Thursday's preseason finale against the Eagles.
Jets linebacker Troy Davis was forced out of Friday's preseason game against the Giants with an upper left leg injury. Davis sustained the injury in the first half and was escorted back to the locker room for further evaluation. He was ruled out for the remainder of the game.
The Colts put running back Vick Ballard (Achilles), offensive tackle Ulrick John and running back Deji Karim on injured reserve, ending their season. The team put fullback Stanley Havili on the Reserve/Physically Unable to Perform list, meaning he's out for at least the first six games.
