Sonia Bompastor says Naomi Girma missed Chelsea Women's match against Tottenham because of a small calf injury sustained before the international break.
The official club update explains the defender's absence but does not provide a detailed diagnosis or a return date.
Depth helps after international duty
After the 6-2 victory, Bompastor praised the fresh energy supplied by substitutes.
Sjoeke Nusken and Maika Hamano both scored after coming on, while Erin Cuthbert made her first appearance of the season.
The coach said the quality of available alternatives was particularly valuable after the international break.
Those comments describe Chelsea's squad options; they do not establish when Girma will be available again.
The match was Bompastor's 50th in the WSL. Chelsea had five wins and one draw from their first six league games.
Individual quality within the team
Lauren James scored two individual goals, drawing praise for her ability to create opportunities from difficult situations.
Bompastor also emphasised the work of the surrounding players, arguing that strong individual displays are supported by the collective performance.
She said James had benefited from her recent England appearances before returning to club action.
The coach praised the Stamford Bridge crowd and credited both teams for contributing to an entertaining eight-goal match.
The update therefore combines a specific explanation for Girma's absence with an assessment of squad depth and performance. Further information on the defender's availability remains subject to another club announcement.
