The Cowboys have signed 25-year old TE Martin Rucker.  Rucker came out of college with the reputation of being a big time receiver but he has not showed that in  the NFL as of yet.  He played in 5 games (1 start) in 2008 for the Browns and he caught 2 passes for 17 yards (8.5 avg).  It was a smart move to take a flier on a guy like Rucker who is likely much better than he has shown so far in his NFL career.
