Crawley have completed the signing of former Swansea defender Joe Walsh on a free transfer.
The 20-year-old has signed a one-year-deal with the option of a further 12 months.
Walsh, a Wales Under-21 international, left Swansea this summer after making just two appearances.
And Reds boss Richie Barker told the club's official website: "Joe is someone I have been aware of for a while and when I knew he was available it looked a good fit.
"He is good cover for the two centre-halves and Mat Sadler at left-back."
Walsh said of his time at Swansea: "Although it was great to train with a lot of quality players it was hard to get too many chances so I had to move on really."
