"I anticipate being 100 percent before camp," he said. "By camp, I definitely feel I'll be at 100 percent. I feel very good with where I'm at. By camp I'll be full go."
Seven months removed from surgery, Alonso said he's rehabbing "four-five days a week" but didn't say how much running he's able to do at this stage.
It can often take players more than a year to regain their full form after an ACL tear, especially at a position in which starting-and-stopping is vital.
One benefit for Alonso is that when he does return to the field he shouldn't have much work to re-learn his inside linebacker spot with coach Rex Ryan taking over. Alonso's role should be similar to the one he played under Ryan's former protégé, Mike Pettine, in 2013.
