Cowboys trade CB Anthony Henry for QB Jon Kitna

IRVING, Texas (  - The Cowboys and Lions pulled off a huge trade last season.

They've just completed another big one Saturday.

The Cowboys have sent cornerback Anthony Henry to the Lions in exchange for veteran quarterback Jon Kitna. However, there could be some more moving parts to this trade.

Kitna, although expected to back up Tony Romo, will reunite with wide receiver Roy Williams, who was sent from the Lions to the Cowboys for three draft picks last October.

The move is somewhat surprising considering the Cowboys appeared content to keep Henry as the starting right cornerback. There had also been discussions of moving Henry to free safety.

Instead, the Cowboys have sent him to the Lions.

Henry was entering the final season of his five-year deal he signed in 2005. He was expected to count $3.6 million on the salary cap this year - with a $2.6 million base salary and a $1 million roster bonus due in June. Overall, Henry's cap hit was scheduled to be $5.6 million; now it will count about $2 million.

Kitna is also entering the final year of his deal, and his $1.95 million base salary will be on the Cowboys' books next year.

The veteran quarterback spent most of last season on injured reserve because of a back injury, though Kitna publicly said the injury didn't warrant being shelved for the season.

Without Henry, the Cowboys are apparently ready to call on second-year veterans Orlando Scandrick and Mike Jenkins to possibly replace him at right cornerback. Terence Newman is expected to return as the Cowboys' starting left cornerback, but like Henry, he has also been somewhat injury-riddled the last few years.

Henry did start all 16 games in 2008, recording 55 tackles but just one interception. He tied for third on the team with seven pass deflections, but did have two sacks.

Given the talks of Henry maybe moving to safety, this trade could mean the Cowboys won't be parting ways with strong safety Roy Williams. The Cowboys could save $2 million in cap space by either trading or cutting the veteran, who spent most of last year on injured reserve after breaking his forearm on two separate occasions.
