Philadelphia's DeSean Jackson has built a reputation as a big-play peformer for his work as a receiver and kick-returner. Jackson showed in the third quarter that he can block, too. Jackson had a key block on LeSean McCoy's 45-yard catch-and-run play in third quarter. Jackson tied up Cowboys' cornerback Terence Newman and would not let him get free. McCoy's big gainer, aided by Jackson's block, led to the Eagles' first touchdown and first lead of the game, at 13-10.
