SPL round-up: A late Stephen McManus header gave Celtic a share of the spoils in a 1-1 draw with against Hearts at Parkhead and maintained the champions' four-point lead over rivals Rangers at the top of the Scottish Premier League.

A fine Andrew Driver goal after 23 minutes put the visitors ahead with only a great save from Artur Boruc before the break preventing him getting a second.

But Celtic came back strongly in the second half with McManus in the right place in the 78th minute when substitute Georgios Samaras, on for Shaun Maloney, headed back Shunsuke Nakamura's cross to set up an easy chance for the Parkhead skipper to draw the home side level.

Earlier this afternoon, Rangers manager Walter Smith told his players to "toughen up" after frailties in the air cost them more points. Smith's men conceded two goals from crosses within four minutes at at Dundee United today before battling back for a 2-2.

Kris Boyd volleyed them ahead early in a first half they controlled, apart from when Allan McGregor saved brilliantly from Jon Daly's free header.

That was a warning they did not heed as Lee Wilkie and Warren Feeney both converted deliveries from Paul Dixon to put United in front within nine minutes of the restart.

Kyle Lafferty levelled in the 76th minute and Rangers failed to convert their late pressure.
