Liverpool fullback Glen Johnson is expected to be ruled out five weeks with a hamstring injury.
Johnson made his first appearance of the season at the Britannia Stadium on Saturday, as an 81st-minute substitute for Martin Skrtel, having been out for five weeks with a hamstring problem suffered in a pre-season friendly against Valencia.
Johnson damaged the hamstring again during the cameo appearance and, though Liverpool do not expect to receive the results from his medical assessment until Tuesday, the recurrence is likely to rule the 27-year-old out of Kenny Dalglish's plans for a similar period.
