LONDON (AP) — Sidelined by a bum knee and slowed by a bad back, Tim Henman is in tough shape heading into the US Open.

Once among the top players in the world, the four-time Wimbledon semi-finalist has fallen to No. 92 in the rankings. His slide prompted reports he might soon retire, and Henman planned to discuss his tennis future tomorrow.

"Because of the recent press speculation I will be holding a press conference in New York ahead of the US Open ... to discuss my plans for the remainder of 2007," Henman said on his web-site. "Until then, I'll continue to work hard on regaining full fitness ahead of the US Open."

The 32-year-old Henman is entered in the US Open, which begins on Monday, and is scheduled to play for Britain against Croatia next month for a spot in the Davis Cup's World Group.

The Times of London and the Daily Mirror reported that Henman will quit after the Davis Cup series, which will be played at the All England Club. But Lawn Tennis Association chief executive Roger Draper said Henman has not yet made a final decision about his future and could take one more shot at Wimbledon next year.

Sidelined with a knee injury at the beginning of the season, Henman has been a far cry from the player who reached the Wimbledon semi-finals in 1996-97 and 2003-04.

In June, Henman lost in the second round at the All England Club for the third straight year.

"I still really enjoy practising and training and also playing matches. It's just frustrating that my body has struggled to cope with what I've been asking it to do in the past couple of years," Henman said.

"Having a family has certainly changed the way I look at the world and also to a certain extent my priorities in life, but I would not go so far as to say that it has diminished my hunger for the game."

Still, he is 5-11 this season and finding it hard to stay healthy.

"I was also planning to play in New Haven this week but I had to pull out because I'm having a few problems with my back," Henman said. "I'm not fully fit, so my focus at the moment is to try to get my back sorted out and then to take it from there."

Throughout his prime, Henman was looked upon as a saviour for British tennis fans who were desperate for the first homegrown Wimbledon men's champion since Fred Perry in 1936.

He's played in 14 Wimbledons, losing in the quarter-finals four times to go along with his four semi-final appearances. Henman also reached the semi-finals at the French Open and US Open. He's won 11 singles titles in his career, and his highest ranking was No. 4.
