Is Lehmann injured? Poom loan to Everton died on Wednesday

So it's finally been officially revealed that Everton's move for Sander Westerveld was initiated after the deal to take Mart Poom to Merseyside died. Surely this supports the rumour that Lehmann's injury sustained against Real Madrid is serious enough to keep him out of the first team. This would mean Almunia moving up to #1 and Poom sitting on the bench as backup. You can understand Wenger not wanting to take a risk since Vito Mannone is our next keeper down the order after Poom. Mannone is a great talent but nowhere near ready for the first 11. Shame Poom couldn't move though since he obviously could do with a few games to keep him fresh.
