Keane hit the ground running at the Hammers after signing on loan from Tottenham, scoring on his debut and impressing in his second appearance before picking up the injury in training, ruling him out for just over a month. That meant the Republic of Ireland striker had to watch from the sidelines as his new team-mates went on a four-match unbeaten run that saw them climb to 18th in the table and almost reach the semi-finals of the FA Cup. The 30-year-old made his comeback off the bench in Sunday's defeat at Stoke before scoring in a hour-long appearance in the reserves' 4-2 victory against Newcastle on Tuesday night. He admits the injury was hard to take but is now looking forward to winning back his place in the side. "The injury is fine now," Keane said on West Ham's website. "It has obviously been frustrating. You come to a new club and you want to play as soon as possible and you get injured. "It is nice to get back and be able to get another 60 minutes. I am looking forward now to pushing on. "It is always nice to score whether it is a reserve game or first-team game but the most important thing for me was getting as many minutes as I could under my belt." Keane will now hope to continue his recovery by playing in the Republic of Ireland's Euro 2012 qualifier with Macedonia a week on Saturday, and the friendly against Uruguay the following Tuesday. He will not be available for West Ham's Premier League match against Tottenham this weekend under the terms of the loan agreement with his parent club, but could start the Hammers' next game with Manchester United at Upton Park on April 2. But with Demba Ba and Carlton Cole both finding form in his absence, Keane concedes he may find it hard to push his way back into Avram Grant's starting XI. "It would be nice (to play against United) but it is up to the manager," Keane added. "The lads have been doing tremendously well, so first of all I have to work hard to get back in the team. Hopefully that will be sooner rather than later." Keane's fellow striker Frederic Piquionne is a major doubt for this Saturday's clash at White Hart Lane due to a foot problem, it has emerged. The Frenchman suffered the injury during Sunday's defeat at the Britannia Stadium and is unlikely to play against Spurs. With Keane unavailable, Grant is likely to play Demba Ba, Victor Obinna and Carlton Cole up front as the only other strikers he has at his disposal are youngsters Freddie Sears and Zavon Hines, who have both been used sparingly this term.
