Boss Jose Mourinho expects striker Diego Costa to feature at least four more times for Chelsea before the end of the season.
The Spain international aggravated a hamstring problem in last weekend's win over Stoke City but could be back for the home game against Crystal Palace on May 3.
"Everybody else [besides Diego Costa] is fine and ready," Mourinho said.
"[John Obi] Mikel is ready, [Cesc] Fabregas with a mask is ready too. No problems.
"Diego [Costa] will certainly be back.
"We have eight matches to play, and if he plays four it's normal. If he plays three it's a little bit below what I'm expecting, and if he plays five it's a little bit more than what I am expecting. I am thinking four matches."
Meanwhile, the Portuguese admits Queens Park Rangers will be desperate for points when they host his side at Loftus Road next Sunday.
"Obviously it's very important for both teams," Mourinho added.
Nobody is expecting an easy match. Last weekend we played against a team that is very stable in the middle of the table and they were fantastic in their approach, their commitment, trying to win the match or not losing it. That's proper football.
"I know QPR have [played] one more match than the teams that are competing with them. Everybody knows they need points in the remaining six fixtures they have, so we know it will be a difficult game for us.
"It's a three-point match and we have to play with our maximum power to try to get them."
