Luke Donald remained in contention at the RBC Heritage with a second-round 68 to move within one shot of the lead.

Donald disappointingly tied for 25th at the Masters but has looked in good form in South Carolina, shooting five-under-par over the opening two rounds.

Steve LeBrun, Charley Hoffman and Kevin Streelman lead but 2011 champion Brandt Snedeker looks set to miss the cut.

The second round did not finish on Friday however, with play suspended due to storms approaching.

Donald, 35, followed up his first-round 69 with five birdies and two bogeys to move up the leaderboard and tie for fourth alongside American Bill Haas.

The Englishman is the only non-American in the top five, with Hoffman, Streelman and rookie LeBrun leading a congested leaderboard. There are a further 21 players within three shots of the lead.

Northern Ireland's Graeme McDowell is among those within a few shots of the lead after scoring a second-round four-under-par 67, one of the best rounds of the day. He is on four under, two shots adrift of the leaders.

Fellow Brit Brian Davis was not able to replicate his first-round performance however, his second-round 75 cancelling out the six-under-par 65 that saw him overnight leader on day one. His round included four consecutive bogeys on his final four holes to leave him two-under-par.

Australian Marc Leishman is a notable contender after shooting a level-par 71 in the second round to remain four under - two shots off the lead - just a week after finishing tied for fourth at Augusta alongside Tiger Woods.

Compatriot Jason Day, who finished third at the Masters, is two shots further back on two-under.

With 17 players still to finish their rounds after play was suspended, the cut has not yet been set - but with the projected cut at one over, Snedeker could miss out on two over.

Snedeker, the highest-ranked player in the tournament, failed to recover from his first-round 73 and could only card level-par on Friday.

Those waiting to finish their second rounds are scheduled to begin at 13:00 BST.
