Southampton and West Ham shared the points at St Mary's on Saturday with both clubs edging closer to Premier League safety.
The first half produced little action as both sides struggled to create and clear-cut chances - Nolan and Lambert going closest for each side respectively.
Gaston Ramirez put the hosts ahead just before the hour mark but Andy Carroll was on hand to equalise with a free kick minutes later in a result that leaves the Saints and the Hammers still not quite safe.
James Tomkins slid in with a perfectly timed tackle to block an early effort from Lallana as the hosts started brightly - but Saints' midfielder Morgan Schneiderlin then picked up a needless booking for a blatant dive.
Kevin Nolan then forced Artur Boruc into a decent low stop, which he just about kept hold of, before Ricardo Vaz Te fired just over for the visitors.
Back came Saints, though, as Jack Cork and Lallana linked up well, but the former couldn't quite get on the end of the latter's cross after a neat one-two.
After the bright opening 10 minutes the game became rather scrappy with West Ham failing to hold on to the ball and Saints not doing much better.
With about five minutes left in the half Jussi Jaaskelainen got down low to deny a toe-poked effort from Rickie Lambert's outstretched boot, the keeper stopping the ball right on his line, before the forward headed just wide right before the break.
Carroll had a great chance to open the scoring soon after the restart but dragged his effort horribly wide after being allowed space in the penalty box.
With the hour mark approaching Ramirez finally got the breakthrough, the Uruguayan smashing the ball past Jaaskelainen after his initial shot was blocked.
However Saints were not in front for long as Carroll levelled with a low, driven free-kick that crept past the wall and beyond Boruc. Both the keeper and Steven Davis, who broke from the wall, may have done better.
Jay Rodriguez was introduced for the hosts as they searched for a reply, and the forward threatened with a few decent runs, however the Hammers defence remained firm.
