Newcastle United will have to wait to find out the extent of the Achilles injury that Steven Taylor picked up against Chelsea.
The defender limped off toward the end of the Magpies' 3-0 home defeat.
Reports have speculated that the 25-year-old, who is due for a scan, could be out for a few weeks or until the end of the season.
United centre-back Fabricio Coloccini was also taken off with an injury during the match at the Sports Direct Arena.
