The Cowboys took a look at former British discus Olympian Lawrence Okoye on Tuesday and liked what they saw enough to give Okoye another chance to extend his professional football career.

The team announced on Wednesday that they have signed Okoye, who had previous stints with the 49ers, Cardinals and Jets in his attempt to transition to life as a defensive lineman. Okoye saw action for the 49ers in the last three preseasons, but has not appeared in a regular season game.

Okoye’s mixture of size and athletic ability are obviously intriguing to NFL teams, but they haven’t translated to success on the field yet. That may prove to be the case in Dallas as well, but it won’t hurt them much to see if there’s anything that can help a thin defensive line.
