The midfielders clashed heads in an innocuous training ground incident this morning. Howell's injury required seven stitches while Clements received a deep cut to the nose.
It now takes the total number of injured players to nine, with the above duo now joining the following players in the physio's room: Alan Marriott, Ross Dyer, Jamie Hand. Nick Wright, Luke Jones, John Thompson, Exodus Geohaghon.
In better news, midfielder Gary Roberts has resumed light training.
