DAVID Howell has pulled out of the Porsche European Open with a back injury just seven holes into his second round in Hamburg.

The 42-year-old, who has struggled with back problems previously, was four-over par for the day and nine-over for the tournament.

"It's just a sore, tight and uncomfortable back unfortunately, I'll take time off now to rest and get strong," said Howell. 

The injury becomes the latest for the two-time Ryder Cup winner, who has also been hampered with a hip problem this season. 

His first day in Germany was less than ideal for the Broome Manor pro, after he carded a five-over-par opening round of 77.

This morning, his struggles continued, as he hit a bogey-five on the second, before back-to-back bogeys on the par-four fourth and par-three fifth.

From there, Howell managed to steady the ship with two par-fours, but then called it a day on the seventh hole.

The Swindon star will now take three weeks off in order to recover.
