Lincoln City striker Geoff Horsfield is set for a two-week spell on the sidelines with a calf injury.
The veteran frontman was replaced at half-time during Saturday's 3-3 draw with Bournemouth after picking up the problem.
"Geoff's really sore and undergoing treatment at the moment," said manager Peter Jackson.
"We anticipate two weeks. It might be sooner, it might be later, we'll have to assess it as the week goes on."
