Robbie Keane will go for a scan on his damaged ankle later today.
The Irish star hobbled off after 35 minutes of last night's clash against Newcastle United after struggling to overcome the effects of an early tackle from Titus Bramble.
Boss Glenn Hoddle explained last night: ""Robbie will have a scan in the morning and we won't know until then. We just hope it is not long-term.
"He could be fit for Saturday but at the same time, he could be out for 10 days. It's too early and we'll wait for the results.
"It's an ankle injury and to lose him so early was difficult. Doc came on, worked hard and did well but Robbie has been instrumental at home, he's scored a lot of goals and that was a big adjustment we had to make.
"Steffen Iversen has a slight dead leg and that's why he wasn't available so we've got a bit of a problem with how we're looking up front."
