New York Jets star wide receiver Santonio Holmes won't be ready for the start of training camp due to a foot injury.

It's not a surprising development.

Holmes could begin training camp on the active-physically unable to perform list due to his Lisfranc injury.

“I don’t have a target date,” Holmes told reporters. "I don’t want to do anything to jeopardize myself being ready for the season. It’s just getting back into the swing of walking and running without any pains from having scar tissue build up around the injury.

"It’s really difficult to learn how to walk again. To do so much balance work, you don’t realize what you have until it’s gone. To lose a ligament and have separation in your joints, have screws placed in."

At least two men need Holmes to get healthy and provide a deep threat: Jets coach Rex Ryan and embattled quarterback Mark Sanchez.

Their jobs may depend on his productivity.
