IRVING, Texas -- The Dallas Cowboys did not wait long to fill Kyle Orton's roster spot, adding tight end Dallas Walker on Thursday.
Walker worked out for the Cowboys in June along with tight end Dominique Jones and guards DeMarcus Love and Garrett Reynolds, but the team passed at the time. Orton was officially released on Wednesday.
Walker spent time last season with the San Diego Chargers after going undrafted in 2012. He started his college career at Memphis as a quarterback and receiver but played three years at Western Michigan as a tight end.
The Cowboys were looking to add numbers to the tight end spot for training camp with only Jason Witten, Gavin Escobar, James Hanna and Jordan Najvar on the roster.
