Didn't see it posted here on the board. Sorry if it's a repost. Cowboys sign free-agent lineman 01:39 PM CDT on Thursday, May 20, 2004 By MATT MOSLEY / ************** The Cowboys have signed rookie free-agent guard Thomas Herrion, who played at Utah. Herrion (6-3, 334) was one of seven players the Cowboys brought in for a weekend tryout during last month's rookie minicamp. The weekend tryout players are usually brought in to provide extra bodies, but Herrion appeared to have a solid three days. Herrion had his head buried in a thick Cowboys playbook when he wasn't practicing. He'll have an outside shot at making the team because the Cowboys need depth behind left guard Larry Allen and right guard Andre Gurode.
