Inverness Caledonian Thistle handed Celtic a shock 1-0 defeat in the Scottish Premiership on Saturday as the Hoops paid the price for fielding a weakened side at the Caledonian Stadium.

With Tuesday's crucial Champions League play-off second leg against NK Maribor in mind Celtic made no fewer than 10 changes while Inverness stuck with the side that defeated Motherwell last week.

However, the gamble failed to pay off as Eoghan O'Connell's own goal in the 65th minute handed Inverness their first win against Celtic at home since May 2011.

The Hoops had scored in their previous 58 league matches but they lacked the invention and urgency to find a way past a disciplined Inverness defence.

The win sends Inverness four points clear of Celtic at the top of the Scottish Premiership, albeit they have played a game more than the Glasgow giants, as they equalled their club record of five consecutive clean sheets.

Celtic manager Ronny Deila handed rare starts to teenagers O'Connell and Liam Henderson but it was the home side who started the brightest and Greg Tansey sent a 20-yard free-kick narrowly wide before his fierce effort from even further out went close.

Celtic were next to threaten with Inverness keeper Dean Brill having to be alert to tip a hooked shot from Efe Ambrose over the bar before making a superb double save to deny Teemu Pukki twice from close range.

Inverness were appealing for a penalty in the 28th minute when Ryan Christie went down following a challenge with Filip Twardzik but referee Bobby Madden waved away their protests.

Nir Biton sold his marker a dummy before he sent a curling shot off the crossbar in the 35th minute as Celtic then came close to breaking the deadlock.

Charlie Mulgrew then popped up to clear Gary Warren's looping headed effort off the line after the Inverness man connected with Graeme Shinnie's corner.

Celtic brought on Stefan Johansen and Callum McGregor at the break as they looked to grab a winner but it was Inverness who made the breakthrough in the 65th minute.

Marley Watkins turned Johansen on the right wing before delivering a dangerous ball into the box. Lukasz Zaluska got to the ball ahead of Billy McKay, who threw himself at the ball in a desperate bid to make contact, but the keeper's clearance hit off the shins of his own defender O'Connell and into the net.

Anthony Stokes was immediately brought on for Leigh Griffiths and almost had an instant impact as he played a clever ball through to Kris Commons but his team-mate's effort was held by Brill.

Caley Thistle should have doubled their advantage in the 76th minute when Dylan McGeouch was robbed of possession in his box only for Christie to send his snap shot inches wide of the post with the goal gaping.

Zaluska made a superb save to stop a stinging shot from Nick Ross two minutes from the end as Inverness finished strongly.
