England striker Jermain Defoe's penalty earned Tottenham a replay in a dour, hard-fought draw at West Brom.

Baggies striker Robert Earnshaw had already hit the bar before sneaking in between Antony Gardner and keeper Paul Robinson to volley his side ahead.

Defoe picked himself up to score from the spot after Darren Purse's ill-timed challenge brought him down.

Jonathan Greening struck the post for Baggies as they sought to win the game but Spurs held on for a replay.

Buoyed by their win over Manchester City, West Brom made a confident start and Earnshaw wasted a chance to give them an 11th minute lead with a weak volley after Jonathan Greening's cross drifted through to him.

Earnshaw went closer on 14 minutes when he escaped Anthony Gardner's attentions to shudder the crossbar with a thumping effort.

But the little Welsh striker's persistence paid off on 17 minutes when he took advantage of dithering between Gardner and Robinson to volley in Ronnie Wallwork's cross for his eighth goal of the season.

Spurs clawed their back into the game and were level on the half hour. Purse's mis-timed challenge sent Defoe tumbling in the box, who picked himself up to drill home the penalty low to Russell Hoult's right.

Referee Mark Halsey waved away penalty appeals as Spurs again struggled to cope with Greening's cross and Erik Edman appeared to grab a piece of Earnshaw's shirt to deny him a clean strike at goal.

Defoe had a golden chance to put Spurs ahead soon after the restart, but he uncharacteristically blazed wide of the target after Simon Davies's neat reverse pass played him in.

Gardner's foul on Zoltan Gera gave Albion a free-kick in a promising position, only for Neil Clement to blast his shot into the wall.

West Brom twice came close to taking the lead on the hour, with Greening first thumping a 20-yard shot against the foot of the post, and then Robinson saving well from a trademark Kanu run.

Spurs defensive wall again did its job when Davies fouled Kanu 19 yards out, standing firm to block Gera's shot, and earn the chance to take the Baggies back to White Hart Lane for a replay.

West Brom boss Bryan Robson. "Darren Purse said he never touched Defoe, while Rob Earnshaw was tugged as he was about to score. "They were two key decisions that went against us, and I'm disappointed because we did enough to win.

"I didn't particularly want a replay, but it won't hinder us, the players can recover and I would rather be in the FA Cup than out of it."
