It was another frustrating afternoon for Terry and his Chelsea team
By Paul Fletcher
Chelsea's run of Premier League games without a win was extended to four as they were held at home by Everton.
John Terry hit the crossbar before Didier Drogba scored a penalty after Tim Howard fouled Nicolas Anelka.
Everton struck the post through a Jack Rodwell header in the second half while home team defender Ashley Cole failed to convert a low cross from six yards.
Jermaine Beckford then headed a late equaliser as Chelsea missed the chance to return to the top of the table.
With Manchester United's match at Blackpool postponed, victory would have meant that the Blues returned to the top of the table, but instead they slipped to third, with Arsenal moving up to first after defeating Fulham.
Chelsea faded after the break and it was Everton who finished the game on top after substitute Beckford scored his second Premier League goal to give David Moyes's team a deserved draw.
The London side have picked up only five points in their last six top-flight matches and it was a glum-looking Carlo Ancelotti who shook the hand of managerial counterpart Moyes at the final whistle.
Everton have also been in poor recent form and have now gone six games without victory, but they can take encouragement from their second-half performance, during which left-back Leighton Baines delivered a series of excellent crosses.
The Toffees lost 4-1 at home to West Brom last weekend and boss Moyes, in charge of the visiting team for the 400th time on Saturday, made five changes for the match at Chelsea.
It almost paid instant dividends as recalled striker Louis Saha forced a save from Petr Cech with a crisp 20-yard strike inside the first minute.
Poor second-half display frustrates Ancelotti
A scrappy period of play followed before Chelsea, with the influential duo of Terry and Michael Essien back after injury and suspension, took a grip on the match.
Phil Jagielka cleared after Howard had lost the ball, Anelka shot wide, Salomon Kalou could not keep a glancing header on target and Terry was unfortunate to see a precise clipped strike rebound off the crossbar.
But Drogba would not be denied from the penalty spot with a fierce strike shortly before the interval as the Ivory Coast striker scored his first Premier League goal since he found the net in the win over Arsenal on 3 October.
There was no doubt about the decision to award the spot kick after Howard clumsily brought down Anelka following an atrocious attempted backpass from Toffees skipper Phil Neville.
However, referee Lee Probert should arguably have sent the Everton keeper from the field as he had denied Anelka a clear goal-scoring opportunity.
Everton improved markedly after the interval and were extremely unlucky not to equalise when the unmarked Rodwell defeated Cech with his header but saw the ball hit the post and run across the face of goal.
The chance had come from a cross by Baines and another teasing ball in from the left-back was met by Seamus Coleman but saved by Cech.
Baines was enjoying so much success down the left that Chelsea withdrew right-back Jose Bosingwa for the more defensively minded Paulo Ferreira.
Moyes disappointed not to beat Chelsea
The was a moment of alarm when Cahill caught Cech in the face with his boot as he challenged for a loose ball after a pass from Steven Pienaar.
Cech fractured his skull in 2006 during a match at Reading and now wears a head protector, but after a lengthy break for treatment on Saturday he was able to continue.
Cole should have secured the points but could not convert a low cross drilled across the face of goal by Ferreira. Cole thought he had been fouled by Coleman as he tried to make contact but referee Probert was not interested.
And Chelsea's afternoon suffered a serious blow when Baines finished a weaving run with a teasing cross to the far post that Cahill headed back across goal for Beckford to score with four minutes of normal time left.
For Everton boss Moyes it was another satisfying trip to west London - this was the fifth consecutive season in which the Goodison Park outfit had left Stamford Bridge with a point.
