Juventus twice came from behind to deny Reggina a much-needed win in their fight against the drop, but the draw will have done little to ease the pressure on boss Claudio Ranieri.
Juve were knocked out of the Coppa Italia in midweek and a haul of three points from four games in Serie A has all but ended their title hopes.
The Turin club issued a statement last week denying they are looking for a new coach, but this display will have done little to appease those who are questioning whether Ranieri is the right man for the job.
Antonino Barilla opened the scoring for the hosts, who are now six points from safety at the foot of the table after being denied a second straight win.
Alessandro Del Piero levelled from the spot three minutes after the break, but Emil Hallfredsson restored Reggina's lead.
The basement boys could not hold out for the win, though, as Cristiano Zanetti equalised in the 73rd minute, although it was not enough to stop the Bianconeri slipping two points behind second-placed AC Milan.
Indeed, the point does little to help either side's cause, with Reggina's fellow relegation strugglers Lecce, Bologna and Torino all winning.
Vincenzo Iaquinta tested Reggina keeper Christian Puggioni in the ninth minute after getting on the end of a long ball from veteran Czech midfielder Pavel Nedved, but Juventus found themselves behind in the 27th minute.
Barilla headed home are the far post from Daniel Adejo's cross from the right.
Puggioni saved from Nedved and Del Piero went down in the area as the visitors pressed for a response, but Fabio Ceravolo came closest to increasing Reggina's lead on the counterattack when he dragged his right-footed shot wide.
A clever move by Iaquinta then created a great opening for Mauro Camoranesi, who mis-hit his shot.
Juventus were ahead in the 48th minute, though, as Del Piero held his nerve from the penalty spot after Iaquinta had been impeded by Daniel Adejo.
If Ranieri's men expected Reggina, who have won just four games all season, to crumble they were in for a shock.
Instead, in the 69th minute, Hallfredsson let fly with a fierce long-range drive with his left foot which beat Gianluigi Buffon.
It looked as though the hosts might be in line for vital three points, but their hopes were dashed just four minutes later.
Moments after superbly keeping out Iaquinta's effort after the Italy striker had turned and shot, Puggioni was beaten by Zanetti.
Substitute Amauri almost snatched victory for the visitors in stoppage time only for his header to fall agonisingly wide.
