Chris Perrior, 15, formally joined Second Division Walsall FC when he signed schoolboy forms in front of almost 6,000 fans before Saturday's home game against Brentford.
The midfielder was invited to join the Saddlers school of excellence after scouts spotted him playing for the Walsall Schools representative side.
Chris, of Beechdale, Walsall, who was born with his right arm finishing just below the elbow, said: "All the lads I play against just treat me as normal, and it has never caused me a problem."
Walsall's liaison officer, Bill Jones, said: "He's a very good player - we wouldn't have taken him on unless we thought he had a chance of making it.
"Although he has this disability, he does everything for himself and he's not embarrassed by his disability at all. He's very quick, gets good crosses in and he can also defend."Reuse content
