Cowboys sign CB Tyler Patmon

IRVING, Texas -- Tyler Patmon has turned a weekend invite to the Dallas Cowboys’ rookie minicamp into a contract.

The Cowboys signed Patmon, a cornerback, on Wednesday and waived/injured safety Marvin Robinson, who received a $2,000 signing bonus as an undrafted free agent. Robinson hurt his knee in the rookie minicamp.

Patmon started five games last year at Oklahoma State after a three-year run at Kansas. He had 30 tackles, nine pass breakups and an interception in 2013.
