Partick Thistle have signed defender Niall Keown from Reading on a two-year deal.

The 22-year old spent the second half of last season on loan at Firhill, but now joins on a permanent contract for an undisclosed fee.

The centre-half was a key component of Thistle's impressive backline as the Jags secured a top-six finish last term, and his arrival eases the defensive worries of manager Alan Archibald following the departure of Liam Lindsay to Barnsley.
