Cowboys make roster moves, add tight end

The Dallas Cowboys have waived tight end Kevin Brock and wide receiver Titus Ryan, both injured in the Hall of Fame game against Cincinnati.
The Cowboys also announced Tuesday that they've signed free
agent tight end DajLeon Farr.
Brock injured his left ankle in Thursday's preseason opening
win, while Ryan injured his left thumb.
Farr comes to the Cowboys from the San Diego Chargers, who cut
him Aug. 2 after signing him as an undrafted rookie free agent out
of Memphis on May 10. Last season, he had 14 catches for 76 yards
and a touchdown for the Tigers. The Houston native sat out the 2008
after transferring to Memphis from Miami. He had 10 catches for 134
yards and three touchdowns for the Hurricanes in 2005-07
