Anthony McFarland could be expendable in Indy (personal speculation)

It looks like he's still under contract in Indy, but IMO with the emergence of the RC Ed Johnson, McFarland could be expendable. He's just turned 30 and when he was traded to Indy last year, he made a difference in the Def. Any thoughts on him? He is recovering from a torn patella, but that was suffered in TC. Any chance we could trade a late round pick or sign him if he becomes a salary cap cut?
