Getting 2 random players from a server?

    for _, players in pairs(game.Players:GetPlayers()) do
        local p1 = players[1] -- ERROR HERE
        local p2 = players[2]
        if p1.Parent and p2.Parent then
            statustag.Value = p1.Name .. " vs. " .. p2.Name
            Instance.new("StringValue", script.Dueling).Name = p1.Name
            Instance.new("StringValue", script.Dueling).Name = p2.Name

            p1:MoveTo(arena:WaitForChild("Spawn1").Position)
            p2:MoveTo(arena:WaitForChild("Spawn2").Position)
        end
    end

Output says 1 isn't part of players. The point of this script is to get all players in the servers, pick 2 of them and teleport them to the 'Spawns'. Anyone help?
