IRVING, Texas (AP) - The Dallas Cowboys have acquired wide receiver Roy Williams from the Detroit Lions.

The Cowboys on Tuesday traded a first-round pick in 2009, plus a third- and sixth-rounder that year for Williams and a seventh-round pick in '09.

Williams' best season was 2006, when he went to the Pro Bowl after catching 82 passes for 1,310 yards and seven touchdowns. He has 17 catches for 232 yards and a score this season for the struggling Lions.

The fifth-year receiver was drafted in the first round by Detroit out of the University of Texas. He has 262 career catches for 3,884 yards with 29 touchdowns.
