Santos, 37, is a permanent signing from Alfreton Town and can play as a forward as he did against Celtic two weeks ago in the FA Trophy.

Santos has considerable Football League experience and has played for Tranmere, West Brom and Sheffield United.

Gardner, 19, has signed from Leeds United on a month's loan. He has made one appearance for Leeds against Macclesfield in the League Cup.

Both players go in the squad for Thursday's match against Stevenage.
