Dockett has so far lost 15-20 pounds during his rehab from a torn ACL in his right knee, Darren Urban of the Cardinals' official site reports. Dockett relayed Wednesday that the weight loss is intended to improve his quickness and return to the field sooner than expected. As he enters the final season of a four-year extension signed in 2010, he acknowledged that he may have played his last snap as a Cardinal due to a cap hit of nearly $10 million for the upcoming campaign. If he remains in the Arizona desert, though, he'll team with Calais Campbell to form a stout defensive front.
